[0.10.6][slpwnd] Reloading save crashes instantly

[elrond1999]

When reloading this save https://dl.dropboxusercontent.com/u/4724091/New27.zip my game crashes instantly. The only Mod I use is the rail layer. Disabling the mod did not help.

Same crash when reloading the save on 0.10.8. Rewinding the autosaves 1 hour gave me a save I could reload, but then playing an hour forward again the new save crashes. Could be Rail related..

Yes, this is rail related. There is a single rail that tries to register in two segments. I was looking into it for a while but haven't figured it out yet.

Yes I get this Error message now. Now how to find the offending rail Corresponding Save: https://dl.dropboxusercontent.com/u/4724091/New30.zip

Ok I found how to reproduce it. Start from this save: https://dl.dropboxusercontent.com/u/472 ... cover3.zip.

Then put down the blueprint in the toolbar so that the left part matches the rightmost rail.

Then somehow the segments gets messed up and you crash on load..

Could it be that the rail signal on the new section is what's causing it? I notice in the screenshot there are 2 rail signals right after each other when there really only needs to be one. Try removing that before you save and load and see if it makes a difference.

Yes I redid the entire section of rail and now the bug is not appearing anymore. I hope the savegames are enough to reproduce and perhaps fix something. Should be a rare bug

Fantastic, thanks for the hint. I managed to reproduce this and fix the bug. The fix will be in 0.10.9 and the saves will be loadable again. The problem happened when placing two signals next to each other via blueprint. That is actually a non-sense scenario (having two signals next to each other) and there will also be a small fix that will prevent placing blueprints resulting in putting two signals next to each other.

Should be a rare bug

Another bug report already came in for the same thing: https://forums.factorio.com/forum/vie ... f=7&t=5438
