I think the new update maybe causing them to burn instantly now?
This is my config https://pastebin.com/24VM6ZNV
Didn't change anything, pretty sure it worked fine before.
Hobo Barrel and Fireplace burning meat
Hobo barrel is defintely instant burning meat even when its in the blacklist
Try using their Prefab names instead of their Shortname.
Hobo barrel = oilbarrel-fire
Stone Fire Place = fireplace.deployed
