Notice the message from System in the left chat (lower left) - which is so strange as that's the only Bug I've gotten since I last reported yesterday on this site.

Update.

So after finishing Aquatic pets vs. Small Beginnings (which is where I am atm, (making progress in doing Family Battler), I noticed after completing the actual thing in the 3rd try that the Master Tamer I was up against have appear now as a pet battle world quest
Carbonite have registered it as a "Bonus Objective"... I'm assuming that that is because I was in an on-going pet battle while the world quest popped up, hence the error I got and posted in my above thread

Already fixed => #57 use latest Alpha.

I didn't exprience the issue yesterday because I only had a few Master Tamers left to defeat, and none of those popped up as a world quest and the few I did alrdy was a world quest and had like 6hrs left on them.

However.. I'll see what I can do when I do pet battles at a more decent hour instead of 8am server time, in the morning

Thank you for applying a fix so fast, especially here at christmas time.
