Outpost

marburg and me found some kind of fix for this problem, you'll have to do some source editting though

in game.cpp :

// altered by hb XXXXXXXXXX for high level bugfix. Need to divide all xp values in npc.cfg by 100
// iRet = iGetLevelExp(iLevel - 1) + iLevel * ( 50 + (iLevel * (iLevel / 17 ...

not 100% sure, but i think its
11 dex
12 vit
13 int
14 mag
15 char

i suggest to try it out, and for example try to equip the armor with a warrior, if its indeed 13 then he wont be able to wear it, then try to put the armor on with a mage
I am pretty sure that 15 is charisma though, changed values ...
