The new mangrove log cannot be used to craft a campfire.
Steps to Reproduce:
Put 3 mangrove logs, 3 sticks, and 1 charcoal in your inventory (/give)
Try crafting a campfire, but instead of a coal use charcoal
Observed Results:
Campfire can not be crafted
Expected Results:
Campfire can be crafted with mangrove log
Notes:
Campfire can still be crafted with stripped mangrove log and charcoal
A bit of note is that crafting campfires with charcoal using stripped mangrove logs can be crafted, which might be a temporary workaround.
