Unity Crashes when adding new methods to SerializableAction

[NoCultist]

I can add as many as I want if I don't assign anything to them but as soon as I try to add one while there is already one there Unity just freezes for second or two and shuts down without error or anything.

I realize this is a necro and will never see any updates, but it was a good idea.
Shame.
