Hi guys, just here to report something strange that happened.
It's my understanding that when you lose all your buildings and your HQ is destroyed you can then deploy from off map some engineers / strelky.
First of all, sometimes I get 2x Ing and 2x Strelky, and sometimes I get just 2 x Ing.
Anyway, onto the bug...
I had an Ing squad recrew an AT gun, and when my HQ got blown up, I couldn't call in off map Ing's until after my guys in the AT gun were killed.
I *think* the game thought I still had Ing's on the map that could repair my HQ so they didn't give me the option to call them in, however they were all crewing the AT gun and therefore couldn't do anything.
I hope this explanation makes sense, it's not a very easy thing to test...
