I have not played hardcore in v1.9 but this is big talk of this bug in palringo chat. Everybody pissed off about some match where this bug cost them and switching over to pro mode till fixed. Sounds like it is a big bug affecting a lot of people based on what I'm hearing i hope you look into this quickly.
This is great news. Perhaps you can post this in-game notices so people know about this. That way they can know what is going on and when they can start using triggers again.
