Ashley Not sure I understand what you mean.
There's nothing removed from the Spriter animation as I'm just reimporting the same SCML file.
The red sprite is created in Construct (it doesnt exist in the Spriter animation) and added to the container with the Spriter object.
I can get around the problem by removing all non Spriter objects from the container, reimporting the SCML file, then putting the non Spriter objects back into the container. It's a bit of a hassle, but it works.
