i beleave it has a limit on size
.mis no limit
.bms dose have a max limit when you export it out.

too many items on a map you get a error.what the limit is don't know sorry its the same error i use to get making maps for DF:2 max it out, the limit you get that error too. to reduce objects one needs to delete some items from the map thats all look over the .mis for that map see whats not needed then remove them. do a small amount delete as you do try test it,still getting the error delete some more try delete 5 items at a time.
