Because the Editable template is showing how a hero battler (specifically actor #2) can use a characterset battler. Also, the ghost was also set to use a charset battler.
Replace @poses_enemy = {1 => 4} Which says enemy #1 (the ghost) has only 4 poses
with @poses_enemy = nil
and replace @poses_actor = {2 => 4} Yep... this is for Basil, actor #2
with @poses_actor = nil
But that's only part of it. Those statements only told it that you were using 4-pose battlers. You now have to erase the values from the last two Editable Templates... the one for actors alone and the one for enemies alone.
When I mean to erase the values, I do 'NOT' mean to erase the lines, but to merely remove the values within the { } brackets.
Note that the actual values of $ap1 to $ap11 and etc must STILL be in the system otherwise the system would have problems. That's why you can't cut them out, but have to change 'em.
I really should write a pdf book for this thing... :-/
