Thank you lenore for reporting this to us. This sounds quite similar to the report at this link, as the player mentions they get an internal error even with manual battle. They're using Treants as well, and are fighting against Orcs and War Dogs. I believe the two reports are related so I'll close this as a duplicate and we can work on it through that thread.
