OS: Windows 10
lastest steam version

after an artifact is created on the 16th of sandstone (Rorash am, a perfect smoky quartz), the game will crash while saving on the 17th of sandstone or further. it will not crash if you save on the 16th of sandstone even after the artifact is created. it will do it regardless of save compression. only way to avert crashing on any save after 16th it is to delete all of the "unit-xxxx.dat" files in the save

nothing is added to errorlog.txt after crashing

the uploaded file contains both the save from the 16th of sandstone, and everything in my data/installed_mods folder necessary to launch the save (didnt want to upload 2 of my mods to the workshop). let me know if more is needed

probably not relevant but everything was played with temperature off (despite modding in a higher fat melting point, the outside is still hot enough to kill people by melting their fat)
