The Add Deployment Points do not work correctly.
Your points will go up, but they do not apply in fact. It will show up as if you added points, but they are not usable.
Summoned units with the *trainer added points* never arrive and instead bug out and cannot be unsummoned.
I noticed this same problem, at first I thought the new "Prevent Cheats" patch was the cause since the game repairs itself after the cheat activates or only the txt is updated with the cheat. Note: This is in Campaign for me(Any mission). Haven't checked Skirmish(AI) yet
