Hi KingsIsle I just completed the quest Gobb-Ler-Mechanics in Karamell and I did not receive any (xp) into my overflow (xp). I hit level 150 already on my storm while questing in Karamell but the (xp) should still be consuming into the overflow. I think this maybe bugged or broken at max level. Please return the (xp) I lost from the quest listed above to the Paradox boss in Karamell cause I lost a ton of (xp) between then and now. I have stopped questing once I got to Lemuria because I dont want to lose anymore (xp) gain until this issue is resolved and working properly. Thank you for your time and I hope this helps as I have sent a support ticket in to also with the details of what happened. I dunno if anyone else has noticed this but I believe it is a bug once you hit max level.
