Base Defense Bug

Okay this game seems to be getting worse and worse with these bugs. It now with the base defense missions if I try to put down like a gun turret during a battle all of a sudden that’s just stuck and it it even though I reached the maximum limit I can’t edit it off the build mode. Can’t switch weapons heal or do anything cuz it lock me in to put the damn turret down. So then I got myself killed, respawn inside the base and then I could only use one gun and couldn’t do nothing else couldn’t pick nothing up couldn’t heal and then I ran out of ammunition for that gun and then I was just screwed. I managed to win by building turrets and now i can’t loot anything and have to restart the game because I’m stuck in the build mode again!!!
