So I had a problem with node canvas, where I use monomanager events like onfixed update, and when I restart scene sometimes callbacks dont remove themselves from events even if I removed them OnStop in actiontask, so this creates missing refference exceptions every frame.
This looks like a bug to me so I’m reporting it.
My temporary solution to this is editing monomanager and setting them null when scene is loaded.
I’ve also included picture where I subscribe and unsubscribe in action task
PS: Maybe also worth mentioning that I load my scenes asynchronously
