If your pet solo's a NPC you get the exp and rep reward, but cant loot or even skin it.

That's not entirely a bug. It is like this to prevent people from AFK'ing while their pet does the job, Blizzard had decided it'd be that way. The bug here actually is that you get the XP/Rep for it.

There's this bug in battleground where you just revived by the spirit healer, and if you mount up and dismount, you pet dies and you have to manually revive them and they died again when you dismount.
