Rules Changes in Streams

I was watching the Season 2 GM Session #1 stream and they talked about the change to minions not auto dieing at a D4.  It reminded me of another change that was discussed as part of Season 1 that I had thought at the time I needed to remember but I don't now (of course).  I think it had to do with Exclusive Boosts/Hinders but I can't be sure.  Does anyone remember or know what that might have been?  I know it was discussed in the chat for the stream which of course isn't on the YouTube vids and a bunch of episodes are missing from Twitch.  Thanks.

The issue with exclusive modifiers was actually Christopher’s mistake, not a rule change. The starter kit is correct and current on that one.

Ok,  thanks. I remember the discussion but I couldn't remember what the results where.
