I tested gosolo and got various error messages and game freezes. Mostly ever script which has flag 998 set to false will give error. Enhanced commanders, wog chests, and all battle scripts. I also disabled ALL wog scripts, still error once battle starts.

The problem is that when playing with gosolo, battle will display entirely but there are 2 AI's in battle. There will not be automatic battle but real battle, without any human. Therefore wog gets confused.

I assume that the command "gosolo" was created for the purpose of testing AI behavior, both in battle and adventure map. Don't want to critic your choice, but I can't find any reason why anyone would play with "gosolo", as Heroes III AI is awfully scripted and will play much dumber than any human player. Anyway, seems that with wog is not compatible.
