It needed to happen, those MB models were bigger than Ylian males and looked all discomboblated when running.
IIRC all character models had to be rebuilt for CB because a new CEL ... thing ... Crystal Space related part specifically for character models was introduced. I just can't remember running around as a Dermorian in MB, but it must have been that way, because Jamona is older than my PS account.
I do recall though I once accidentally robbed some strangers in Hydlaa. They were trading Crystals, and because there was no trade feature they had to put it on the ground. Because there also was no guard feature, everyone could take it. I just thought "Oh nice, found some Crystals" and took them. Then, they were inexplicably mad at me xD
Those were the days! I wish we could put up an MB server somewhere, that would be awesome![/half-jokingly]
Heh, somebody lock this thread; the original question has been answered and it's off-topic now.
