FunctionClauseError from fsm dependency

[andersonmcook]

We've run into this error twice, once a month ago and again today. It's a low priority, but I just wanted to let you know.

(FunctionClauseError) no function clause matching in EventStore.Subscriptions.SubscriptionFsm.transition/3

It happened both times within about 100 milliseconds in 3 different subscribers (no one subscriber is in both groups).

Sorry, I can't give you much more detail as the error message got truncated and I don't know the args for transition.
