I know why this happens, but that doesn't help fix the problem. I put in a support ticket:
In icebound battleground, I have managed to get permanently stuck with a level that will not end. I believe it happened because of the way that you stage zombies off screen before they become visible. What I believe happened is that a Troglobite was pushing a bunch of frozen Yeti Imps when they ran into a lane change tile. When that happens the Troglobite continues walking leaving the Imps behind. Then what I believe happened is another Troglobite came along with his load of frozen Imps. It got stopped by the other frozen Imps with some still off screen. The Troglobite left them, got killed and now all of the other zombies are dead except whatever frozen Imps are off screen. No weapons continue off the screen to thaw them out. I planted flaming pea shooters in the last column but they are unable to thaw the off screen Imps. There is no way to resign. So I am stuck permanently on this level. Maybe the Imps should thaw after a time if nothing pushes them onto the screen.
Thanks for your assessment! Sounds like what is occurring.
Look, most of us already know this after looking through the pvz wikia forums, but this doesn't tell me how to reset it. There needs to be a way for that to happen so I can retry and keep this in mind. But I need to know how first.
