The server has been restarted to apply a few fixes.
There is an issue with pets in dungeons. Sometimes you enter a dungeon and the pet is nowhere to be seen, but looks like it's summoned because you can see it's unit frame. Opening the pet interface when this happens will crash your client.
Until I fix this issue, active pets now get dismissed when you enter a dungeon. You will need to resummon your pet once inside. If it refuses to summon then that dungeon is bugged and you will probably not be able to use your pets in there, but at least you won't crash anymore.
Daily Gift buttons can no longer be spammed to receive multiple rewards if you have a bit of lag. Don't think I'm not aware of how many of you abused this and didn't let me know about it - all rewards received to the giftbox are logged. Thankfully somebody had a conscience and informed me.
