Whenever an alert (like missing construction materials, turrets engaged etc.) is clicked whilst inside a factorissimo building the game crashes. I suspect this is related to the game failing to open the map of another surface so this might be a bug in the base game.
EDIT: I cannot replicate this issue anymore. I encountered it directly after starting to use the mod with two separate placements of the same building. I have now placed the building again, opened the map inside and successfully viewed an alert. This might therefore be related to an uninitialized map, but I don't know.
