So it's better to have it allocate and free as little as possiable, when doing something that is as freeed and allocated as char_data structs and obj_data structs? I'm still really new to memory allocations. It just seemed to me kinda pointless to keep all these pointers around if they weren't going to be used. But I could see where it could cause small problems *grins* esp if it were windows.
