omg wtf slykaar spawned and he was like 2min delay but he was FRICKING INVISIBLE, it was a pain to find him and kill him while he was teleporting and invisble for some reason

 

Try changing your world, this might be an actual bug if so report it on the forums in the section for glitches, If you are in a boss room in a dungeon you can /class instead of /kill and it will teleport you to the outside the dungeon.

 

Seen 2 of these might be a bug

 

he has vanish spell, makes sense that he goes invisible sometimes
