Would you mind listing all mods you are using (all, no exceptions). It may be anything, FotE is last idea here.

That's the thing, I tried deactivating all mods, deactivating FoTE, etc. Here's the list:

1Fall of the Eagles - Part 1
1Fall of the Eagles - Part 2
Perfornamce Maker For Massive Battles
Sebidee's Better Army Stances
No More Trees

I tried FoTE only and it keeps happening. Raising an army shows different units for bodyguard, but gets cut.

Also, while playing vanilla I don't even get a chanco to choose a bodyguard unit, but with FotE this behaviour happens.
It really shouldn't matter if there are only like, 3 units to choose from, because they are clickable, but I have no way of checking because, again, units get cut off in the UI.

Yeah, seems like hordes have different popup window than settled factions, yet still all 3 options are clickable. I guess nothing can be done about it, however that first unit option is only for faction generals premade in startpos.esf, new ones get only 2 options. I don't know if it can be fixed with hexediting startpos.esf but if you don't play FotE+EP Revised then none fix will be available since pure FotE doesn't use startpos file.

Wait, then this shouldn't happen in FoTE+EP Revised? I didn't try EP, is it nice?
Edit: ah I see the FoTE+EP combo is what people is pouring their love onto. Guess I'll have to try it, it's been a while since I've played Attila modded.

Actually it is rather not repaired there, i just can experiment at later about fixing it, but now other things are prior.
