Thx a lot everyone! The problem must have been to do with deleted units, because I copied the units I had added, pasted them at the top of my backup, and used that as the unit prod. The game worked fine, except for Pronoi Alligion sp?, It crashes at the start of any battle with them in it. But this does not matter as Pronoi Alligion is one of the units I wanted to delete. I will consider all ur points when I re-begin work on the unit prod. Thx again.
