Unexpected error while updating RM 4.0

Can someone help with this? I've tried to look for an undefined device but it seems all devices involved are ok and, in any case, this bug would prevent me from deselecting those objects from settings.

Have tried recreating the rule from scratch?

I have and, of course, it works. But this is not ok with me because if / when this happens with a bigger rule, I'm gonna be pretty annoyed.

I totally agree. It was just part of the whole debugging. And is this an error since an system update? Or don't you know since when. If so, I would recommend reporting to support@hubitat.com

Your video goes by too fast. Can you post a screenshot of the logs and the rule please.

Doesn't it give you the option to play/pause it?
