Factorio v0.17.66 works flawlessly, but v0.17.68 crashes when loading savegame; see console output below. After several iterations of testing different mod combinations I think PyIndustry could be responsible. Removing PyRawOres does not fix the problem. However, after additionally removing PyIndustry (including PyCoalTBaA) as an active mod (on which PyRawOres depends), the savegame finally loads.

Factorio crashed. Generating symbolized stacktrace, please wait ...

that output doesnt really tell me much of anything. did it give an error message. thats usually found in the factorio log file

Here is a link to the complete factorio log file:

ok. so that is from the log and it actually crashed factorio. im not seeing anything that jumps out at me. can you send me the save you tried to load ill need to debug it to see exactly what is going on with it.

Here is the savegame:

Thank you for your help!

Looks like it's a factorio bug and should be fixed in the next release

Thank you for your efforts! Looking forward to the update.
