Your capx requires several third-party addons, one of which is commercial.
If I understand correctly, you added a second character object and it's causing all kind of problems.
I think it would be much easier to have just one character object with multiple animations.
Your animations can be like this:
AssassinIdle
AssassinRun
AssassinAttack
GnomeIdle
GnomeRun
GnomeAttack
Also, add an instance variable "characterType".
As a result, you should be able to add new characters to your game with very minimal changes to your events.
For example:
On Space key pressed -> Character set animation to self.characterType & "Attack"
