If you create a character property like CurrentTarget which will only list one character who could be the players current target or character reference.
And if you want to pass that character reference onto another task via params, currently when entering Player.Propertykey.Name it won't be recognized by the task which is expecting a referenced character.
The called task uses;
# %character% in the general, with character reference restrictions. This throws up an error "Sorry, I am not sure which character are referring to".
Passing on character references from a task that does not use a reference specifically is important for interlinked tasks which relies upon referencing such as a character. Being able to do so from a non-referenced task would be handy.
Remove this bug report. I discovered Player.PropertyKey.Name needed to be Player.Propertykey without the .name on the end of it in order to be passed by a restriction. Sorry about jumping the gun on this.
