to fix the levelcap go into your antrix.conf file and look for this
Code:
# Level Cap
#
# This variable controls the level that stats will be generated up to internally.
# Beyond this level players can still see a higher level visually but their stats won't
# increase beyond this point.
#
LevelCap = 70
simply change the cap to 255.
.mod hp xxx xxx (like .mod hp 12345 12345(now you have 12345 hp))
in terms of items not spawning in use the command
.lookupitem nameofitemhere
it will look to see if you have the items to spawn in. if they are missing or dont exist. (which i've found with some gear) you may need to update your item tables in your database.
