Well the lockdown example was bad cos it's absed on a different group
So, let's see if I got it, you added an option to morph into other units to the lurkers, marines, firebats, and vultures ? Did they all morph in the same unit or in different units ? (just curious).
Well, I'm afraid you can't make that work unless you edit the EXE. You can, for example, select 12 Marines and ask them to morph, but not a Marine and a Vulture.
There is actually ONE way to make this work. If all units have the same buttons. I mean, if you remove StimPack from Marines and have only the morphing, than yes it is possible to have a Marine and a Vulture and whatever else morph.
... but as I said, they must morph in the same unit.
