Found this a couple days ago during an online coding session with my team. I've saved an fsm template, sent it through skype, and when my bud imported it all he got was an empty state. I thought it could be related to some missing custom action, but he sent me a new template which I've then tried to import in the *same* project (we use GIT) and I got the same result.
Needless to say this is pretty bad since we can't share Fsms created separately. Maybe using export packag as mentioned in another thread but still..
