Units Usable on Custom Map Cause Crash on Vanilla Map?

[Qaqophas]

I've made custom maps before, and have been able to use units like Jawas, Gamorrean guards, Acklays, Ewoks, etc... as playable units by editing the XXXc_con.lua (or whatever gamemode/era I want).

After seeing this post: viewtopic.php?f=27&t=16616&p=287596#p287596

I started messing about with changing up the troops on the original maps for a bit of fun. I can do it with most units, however, the Gamorrean guards, Acklays, and Wampas specifically cause the game to crash when I load it up. All other troops work though (for example, I can have Ewoks vs Jawas on Dagobah).

Keep in mind, on custom maps, all units work, and do not cause a crash.

Does anyone know why this might be the case, and how I might go about fixing it (if possible)?

Ok, so I figured it out. For those wondering, Acklays are "walkers" with three pairs of legs, so I replaced what was said in the lua file about walkers (the whole AddWalkers thing) with what was said in a freshly created custom map's lua file.

For the Gamorreans, it has to do with the "combo" stuff in the lua file. So, I added what a fresh custom map lua file says about "combo" into the normal lua file of the vanilla map.
