We had a bug if you copy a race that has multi-event participant caps- the multi-event caps settings copy over, but the participant cap number is removed. This is now fixed.
There was also a big when you adjust the setting and subsequently try to copy over to other events, the Priority Only Registration Ends * time switches back from PM (what I had it set at) to AM. Also, it doesn’t copy over the Priority Registrant List * (it leaves it blank/unselected). This is now fixed as well.
