Exception throw calling: <bound method FireService.flammable_object_location_changed

to be honest at start this is a friend question not mine
im asking in this person place due some people dont like to be in place with cracked games 
the error is

Code:

Exception throw calling:
<bound method FireService.flammable_object_location_changed of
<services.fire_service.FireService object at
0x00007FF416B8B250>> (ValueError: Failed to find/create valid
placement polygon)

is this caused by custom content or its something faulty in game
thanks in advance

"Recommended Action" tells you what to do. It's because of some mod(s), not CC.

thanks i hope that helps
