As things are now, the event sheet tres files' names get set to what seem to be random numbers. I think it'd be better to go with the name of the target scene node instead, but have the random number added to the end. For example, if the scene's name is "GrasslandsFirstArea", the event sheet tres file's name would be "GrasslandsFirstArea_insertRandomNumberHere". If the scene's name changes, best have the tres file's name change accordingly as well.
