I have two ATAT's odfs I made they are the same except one is stronger, How do I make them both apera on the map?

Odf is the same except for a 2 at the end on one, in teh lau I added both to the Imp and still only the original ATAT's spawned. What am I doing wrong?

Any ideas would be greatly appreciated.

You have to change the vehicle spawn in ZE to the new AT AT

Also make sure you made a .req file for your new ATAT, and that you added it to the side.req.
