I've been leveling over 100 pets for a guildie and tonight I decided to give like 30 of those pets the last 1-3 lvls and send them back to my guildie as lvl 25. I'd send two rounds of 12 pets, and then another 9 pets and with sending the last 9, gave the above error.

When I've pets that I lvl with training stones, and they hit lvl 25, and I cage them without dismissing them first, this error pops up:

Cant reproduce. It might be incompatibilty with other addon, check with only Carb enabled.

I think to reproduce it you'd need my pet battle addons as well... Rematch, Battle Pet BreedID, PetTracker
That said, It wasn't an issue before I added warehouse to the mix of addons.

Thanks for checking, but I was done yesterday caging pets for my guilide. Now I only have a few pets left to level :D

So as i said it might be other addon that changes something with events. Without those addons i do not get any errors when caging.

Could be. But a pet battler without Rematch has no idea what they're missing. hehe

I'll leave Warehouse for now and perhaps come back to it in the future.

Again, thank you for the quick reply.
