Bee hives should regenerate health slowly over time (or killer bee hives should be replaceable)

[HumanBean150]

This is mostly a suggestion based around willow and farming embers - bees, especially the killer bee biome, give one of the best ways to farm embers in the game, if you're lucky enough to have the biome in your world.

Over time though, fire damage (either from burnt items falling by the hives or from the hives themselves catching on fire) will destroy some of the hives and make it a much worse method for gathering embers.

I don't personally think that embers need to be any easier to farm than they are at their peak, but it feels a little backwards for them to mostly get more difficult to acquire as a world gets older, unlike pretty much everything else in the game, even if you're being pretty much as careful as possible about the hives.
