Unbeatable in GC

All of a sudden, the teams in levev 2 are mostly unbeatable. I knock them down to 1 re square left, then I can't kill them. I've waste 140 points trying all of my GLs, all to time out the battles. So, 2 questions: 1 Is anyone else having ths sam issue? 2 What's being done about it?

My gp is over 14k, and I usually cruise through with no problems. Now I'm stuck.
