Micropiglets die after capturing their housing
Simple as that.
Simple as that.
Micropiglets respawn fast, if there is any drawback then it's really minor.
But surely it's not a bug.
Not that simple.
It makes things much simpler, because these pigs are only supposed to be eaten by their owner (or grabbed by their owner, or possesed by their owner, ....) they need to be replaced on owner change.
We could "convert" them but this is way more cumbersome.
Why do you think this is a bug?
And why should it bother anyone? It has no drawback for the player.
I suggest to decline.
Definitely not a bug, and another perfect example of something for our suggestion forums.
