Not really. This has to be some bug in the code that either misreads the play area size or jumps too quickly to a conclusion that it is impossible to read that info.
No worries :) It is possible to kill that turret, it requires lots of shooting though. I will be reducing the amount of health for those turrets, so they're easier to kill. It will be still a waste of energy to do so (unless with infinite energy on, then it will require less time :) ).
