There is no freezing at all. What happens is that the screen don't go to the place where the place event is.
However, when I try to start the battle "blindly", I get the following error:
undefined method 'down_case!' for "boss":String
EDIT
Another error found. When I used the summon skill, I got the following error:
undefined method 'spriteset' for #<Scene_Battle_TBS:0x3252ab0>
