Back to this... I have a circuit that sets the depot signal only when the train is present, similar to the example you provided. However, without the depot signal, trains will still go to these stops because the name matches the return stop in their schedule. They arrive, depot signal remains absent...

I don't expect you to fix train loading; that's my problem.

The question is: Why did LTN's "output combinator" change because some wayward assemblers mistakenly dropped something into an arriving train?

The trigger is a few inserters left holding stone, 7 of them to be exact. These get dropped in the train the moment it arrives and causes 7 stone to be added to the LTN "output" combinator even though they're not part of the original request. And it's definitely the output combinator I'm l...

It definitely does. I even removed (actual remove, not just disconnect) everything except the LTN stop and the output is the same.

I've kept the state in a separate save if you want me to check anything else. For now, I'm going to destroy and recreate the LTN stop and see if the problem goes away.

LTN v1.16.7 I'm playing Space Exploration. I have a requester station ("Typhoonator") requesting "core fragments" and a provider ("Vulcanite Core Processing") providing cryonite, stone, and core fragments. (Both stations have incorrect names due to blueprint copying.) F...

The problem was that the save was an Angel/Bob save and I didn't have those mods enabled while trying to load it. After enabling those mods, it loads again.

So it was going to fail but I expect it shouldn't fail quite this way.

I have an old saved game (from 0.18, I think) that I've loaded a dozen times recently (but never saved) so I could copy some old designs. Suddenly it started crashing Factorio when loaded. Attached are the logs taken from crashes just before and just after a full reboot of my machine with no other a...

Thanks for the pointer.

I did consider that but breaking a blueprint into three or four different blueprints, each with a different set of materials just isn't practical. Not only would it be a very time consuming and error-prone manual process but it would have to be done anew any time changes were necessary on the design...

Let me start by saying that Factorio is one of the very best games I've ever encountered and surely the best money I've ever spent given the number of hours I've played. During the development of my self-building mega-factory blueprints ( https://factorioprints.com/view/-MNZWdWosuqr3vtaC2hD ), I've ...

There are a couple LTN log messages on which more detail would be helpful.

"No station providing...": Include the train length limits.

"No train found of length...": Include "cargo" or "fluid" detail.

I looked at something similar but, if I'm not mistaken, it'll still output the depot signal for a single tick. If the caching of the value was done the tick before (when the train landed) then presumably that is sufficient?

It's too bad that LTN can't double-check the "depot" signal before doing the final assignment.

Do you have a recommended circuit for this? I haven't figured out a circuit that's less than three gates while it takes only one gate to turn it off if non-empty.

Factorio 1.1.6 LTN v1.15.0 It seems that LTN will add schedules to trains at stops that were depots but are no longer. I have a circuit that only sets the "depot" signal when there are no train contents at the train stop. The goal is to stop a non-empty train from going out again and deliv...

Thanks. Too bad it doesn't rank it by signal value. That could be useful sometimes. Not a big enough benefit to justify the cpu cycles, I guess.

Factorio v1.1.6 I'm trying to understand how "set filters" works with the filtered-stack-inserter. I know it ignores signals with negative values, but other than that, how is the single item selected from the positive signals? I ask because I have a chain of filtered-stack-inserters with &...

It's not a duplicate report as the original report was about a placed blueprint having to be placed again. I'm telling you that the bug is damaging a blueprint template: a work that is kept around and modified as need be. Blueprints are then taken from that for use in the factory. After the update t...

I added a comment to a "won't fix" bug but I'm not sure it was seen. https://forums.factorio.com/viewtopic.php?f=58&t=91880 This is not a "minor" issue, nor is it always easily corrected. If anyone works with a sandbox that has designs that are fully or partially "ghost&...

This is NOT a "minor" issue, nor is it always easily corrected. For those of us that use a sandbox to work with ghost designs and then create blueprints from those ghost designs, it corrupts the blueprints. If we then share these blueprints, it causes problems for the users of them. Detail...

Here's my method of fixing my blueprints: 1) Make sure the blueprint matches the ghost factory. 2) Destroy the ghost factory. Ensure no "realized" entities remain. 3) Place the broken blueprint. 4) Use a destruction planner to remove poles and substations. 5) Undo! 6) Capture a new bluepri...
