the ubi tokyo express and FOTRS
 

I just reinstalled FOTRS, and can't get the mission to work. It creates 30 copies of each ship but only visually, the copies are not targetable or show up on sonar ect and crash if you fire on one. It works fine in stock. Any ideas why installing fotrs would cause this? Just to make sure, I played the tokyo express in stock, plus I played some other missions in FOTRS and the bug didn't happen.
