Has anyone else had a problem with your human stopping gaining her equipment slots and experience points?
At what level and what were you doing? There's a set of diminishing returns for High Level Characters doing low(er) level scenarios so it may appear you get no XP.
Hey Skip, I am Level 8 doing level 7 quests currently. My Elf Mage, and Dwarf Cleric are not suffering from a loss of XP, and have now passed the Human fighter in levels
XP is based on the individual char's level compared to the module; a level 8 char in a level 7 adventure should have gotten 4 XP. Was your warrior higher level than them before? If so, he would get less XP from the same dungeons. And for equipment slots, warriors get their last one at level 7, priests and wizards at level 8.
"quests" actually don't give any XP to anyone, but "regular adventures" do. If your elf and dwarf and getting xp, then I suppose you meant you are doing level 7 adventures.
I had the same problem once. But i realized it happened because my warrior was one level above my other characters so he got usually less xp from playing an adventure which was confusing. Once you have a significant higher level then the adventure you play, you will get very little or no xp from it, so doesn't have to be a bug.
