I have a theory of steps to reproduce.
The last time this happened I noticed that I was fast replacing a substation ghost with a lighted substation at a point which would join two separate power networks into one.

I'm in a Sandbox scenario map with this mod enabled: https://mods.factorio.com/mod/LightedPolesPlus version 1.7.1, as well as power-grid-comb 1.1.0 and a number of other seemingly unrelated mods. I wasn't using the comb while experiencing the bug, though I had used it previously on one of the networ...

I am running Ubuntu mate distro, and the mate desktop. My window manager is Metacity (Marco). I'm using the laptop keyboard with no modifications. My laptop is an Entroware Aether https://www.entroware.com/store/aether . I should try with an external keyboard! I downloaded 0.17.17 and started a new ...

Sorry for spamming, I'm back again with an update. I noticed that loading a 0.17.16 autosave worked fine, but loading a 0.17.14 save froze again. I'm still plagued with the notion that version bumps might be to blame. The thing is that the 0.16 autosave was made by staying in the 0.17.14 save a litt...

I found "last-played-version": { "game_version": "0.17.16", "build_version": 43906, "build_mode": "steam", "platform": "linux64" } but setting game_version to 0.17.14 didn't cause the changelog popup window to reappear :...

Okay, have manged to load the game successfully. Can't be sure of this (would need to repeat the steps) but I have a theory. Each time I started the game and had this freeze issue there was the changelog popup when first starting the game. When force quitting the game with repeated ctrl-alt-delete e...

What keyboard layout do you use, and have you remapped any keys? Map pings are done by shift-clicking, so it's possible there is some weird modifier key state in effect.

QWERTY. I have remapped some factorio hotkeys but nothing at a keyboard / OS level. Good thought though thank you.

I've just tried on 0.17.16 and this is still happening.
I've just tried twice to load a game and had the freeze occur.

Just quickly, a factorio current.log for the successful load: https://pastebin.com/Nvbq8DQs
As far as I can tell it's exactly the same minus the exiting steam part

Loading Factorio again now for a second attempt (as usual) but trying to be more observant. First thing I noticed: Clicking "Play" at the main menu switched focus back out to this browser, minimising Factorio. But this time it worked, again, as usual. I hope you can shed some light on this...

I have an occasional issue when starting, or loading a game. Factorio appears to run perfectly fine but doesn't respond to any keyboard input. It responds to mouse input, I can click on the map and drag the map view around. Often, clicking on the ground will cause a "map ping" to appear, b...

A science research that upgrades the exoskeletons to provide "belt motion compensation" seems like a good idea.

I applaud these three ideas

I think proposal 4 is successful for its simplicity. To address some reasonable concerns I've seen: Mods mean useless actionbar 'pages' and wasted slots. Limiting the number of blueprints players can keep. I think both of these problems should be solved by modifying the 4th proposal. Have the synchr...

A lot is currently possible by duplicating station names and using circuit signals to enable/disable stations. Like, a lot a lot with enough patience and circuit network ability. However many of us rely on what is possible using the train gui (I was a massive fan of the new wait conditions) My idea ...

Will the artillery train be moddeable? I would love to see a mixture of super long range artillery, mid range cannons and short range gun turrets. Could be fun to orchestrate a creeping train advance. Also an interesting method for flexible base defence. Keep some gun trains in reserve to dispatch t...

Gone but not forgotten.

I've noticed some odd biter behaviour in this version. I made a bug report for it because I had a lot of biters frozen in place on the map, that is unless my player is nearby. I was doing lots of blueprinting in the zoomed in map view around the time (which I love btw!) EDIT: Just checked my bug rep...

Attached is a save where the visible biters are frozen in place on the map. Symptoms: biters visible on map view stopped moving proximity to player unfreezes them (some only temporarily) Actions beforehand: Radars and roboports built using zoomed map view (recently added feature), shift-clicking and...

One suggestion for the rocket/satellites that would add to game play: Have two satellite types: Explorer and Destroyer An explorer would provide radar type functionality, but over a far greater area (simplified, it could cover the whole map, more complex, you could deploy the satellite over a speci...
