Short description of the bug
Tagged mobs and snow golems respawn.

Detailed description of the bug
Name-tagged zombies and other hostile mobs, as well as snow golems, seem to despawn for no reason. This affects lots of farms, that require these mobs in order to work.

I tp'ed to your farm and prism'ed it, it seems they were killed, one by a skeleton and the rest by creepers.
