I decided to post it here instead of the mod topic because no one seems to be having trouble with the mod, probably because most people using it are on Windows.
The game crashes when I try to start it after setting "active: true" for this mod in options.cfg. If I set it to "false", start the game, and enable the mod from the menu, then the game crashes as soon as I click OK. If I do not enable the mod, the game can be played without any error messages in openxcom.log.
Here's the content of the log after the game crashes with the mod enabled:
