I had been backed up into a corner with one of the spawner towers and after breaking it, the game left me trapped in the corner with my health slowly being depleted from barbwire. Now, I don't know if this is the case with all of them but this one particular I got forced into and wasn't able to free myself. Keep me in the loop if anyone else has come across this dilemma.

I have hopefully solved this issue, and it should no longer be a problem with our next patch. Sorry about the negative experience, but thanks for reporting it!
