@ivancea is this in the same line as #132554?

[ivancea]

@astefan This one doesn't look like it. The bug in the other issue was related with AsyncOperator (And any subclasses). But ChangePointOperator doesn't inherit from it, and I don't see a relationship here. Or at least, it isn't clear.

Thank you @ivancea. I'll take a deeper look at it.
