I already stated that the solution to this problem was to "shift" all of
the bits in MOB_XXX up one number. When the way the things are coded you
should NOT use any flags that have been defined as 0.


and shift all other UP one number.

You have to change the spell affects and all other (former) vectors as
you did with the MOB_XXX flags.

Took me 40 hours to get it going on bpl 11 and that's what it was
designed for. I do hope that you're not expecting a short amount of time
to be spent on such a huge undertaking.

Umm.. Trying to remember if AFF_GHOST was a aff1 or aff2 is the worst
side affect that I see. :)

One suggestion that I saw (and am tempted to use myself) was make all of
the MOB_AGGR_[race, align, class] flags one set and the rest of the flags
into another. That should free up tons of room for other flags.
