I think there is a bug while using the path remote controller and set a path. When the vehicle following the set path goes from it's last point to the first one in a loop, it will not avoid obstacles, even though when the option is set to 'always' use pathfinding. Instead it appears to use the optio...

I would like to suggest to treat rails and trains somewhat the same way as a assembler with modules in it. If you build them, first a robot goes there to place the assembler, then another one to insert the modules. If you select trains and rails with no filter, all gets a red cross, but the robots w...

I investigated further, and noticed that it makes no difference if saving automated or manual. Somewhere within the map there are 2 trains colliding, and after that has happened, the game crashes when trying to save. The collision takes place 8 seconds around opening the above provided savegame. ( c...

I have no clue what is causing this crash, but I saved the game exactly 1 minute before my current autosafe will be triggered. I think this way it is easy reproducible because the ingame events will have the same timings. Steps to reproduce: 1) set your autosave interval to 1 minute 2) download my s...

If you have really slow trains it will do, but if you use mods with really fast trains for example, it becomes another story. I think that a train should always check if it even may pass a signal before it reserves the block it wants to enter, even if it already has reserved it before. If the second...

https://forums.factorio.com/viewtopic.php?f=11&t=71409 in this topic in announced a bug where trains are able to pass a red light when it is kept red by circuit logic. at the very moment it had completely left the specific block briefly, another train was able to enter that block. so a collision was...

Why is it important that all waiting bays merge into the same block? How does a signal anywhere on the bypass cause an issue for your circuit control? signalbug2_2.png in this situation some extra signals will be fine by coincidence, true. if the red train got to go it will wait at the red-lined-sp...

sadly no, the stone gets green when the stone signal hits zero ( out of stone ) and the same goes for metal, copper, everything. on that green wire you can find the whole logistic network inventory. I can think of various ways to make it work, involving more circuit logic, or give the waypoint stati...

Is there some reason you can't use the train stops to control your trains (with a circuit condition) instead of the rail signals? I have never really thought about that, I've always used the signals, this way the trains can go forward for about 4 meters, so the waitingbay can be 3 rail segments sho...

the rail system is divided into blocks, formed by (chain)signals. signalbug.png in this example the upper red signal is circuit controlled, to be always red, yet the train goes trough ignoring the signal. it happens because the block the signal is guarding is the same block as where the train just c...

when opening up your inventory you can select any item and it will place the black hand so your robots doesn't fill up that space. this also applies to blueprints and blueprint books. but not always. when your inventory is completely full, then selecting a blueprint (book) from the quickbar does not...

I experience the same thing since a while now,
I put it in suggestions and ideas a few weeks ago.

Escape also works instead of clicking on the map.

the 'creative tools' tab in the crafting menu disappears when you save and load. particularly when you load a save where you use the 'sync mods with save' button and 'Creative Mod' is disactivated. when after that you load the game where creative mod was in use, you have to sync mods with save again...

today I tried turning mods on and off, but I can't figure out which mod is doing this. when I enable the first half it's not there. when I enable the second half and turn the first half off, it's also not there. so apparently it's the combination of all these mods in the save. I'ts not a game breaki...

:lol: noob feelings. yesterday my comuter did something strange, instead of waking up from sleep mode, it started up as if it was off before. factorio was active when entering sleep mode. I had to reinstall factrorio as if it wasn't installed yet, but other steam games were still fine. I also had to...

when you change a train to automatic mode, it checkes if it can enter the next rail block before entering it. but as far as I know, it doesn't check if his current block is occupied so it just starts moving as if he's the only one in his current block. if there was a signal or a chain signal between...

while having items in hand, you can place the actual thing in the world, or place ghosts by holding the shift-key. when you run out of that item, now your cursor gets cleared. then you cannot select that item for building anymore, not even for placing ghosts. you cannot select it in the quickbar nor...

yes, and it was gone, but I'm still sleepy
so tomorrow I try to figure out which mod is doing this

but when opening the save, you are standing next to it, within radar range, so it should update right away

as the title says, I found a bug but it is hiding very well... you can't see it, touch it or shoot at it, and it doesn't attack,
in fact, I don't think it is there, only the map still thinks it is.

here is a savefile, he's standing very close.
