Sometimes crimson forests can be yery hard to find. I know this isn't really a bug but the only food source in the nether is the Hoglin that only spawns in the crimson forest. If you try to play survival but your starting dimention is the nether it is sometimes yery hard to get some food. I suggest that crimson forests will be more common to find of that there will be a new food source in the nether.
I think this may be a duplicate of MC-170827, but I'm not sure.
