Multi-line chat messages broken?

I've been using a lot of "\n" in my ChatMessages in the past to display multi-lined messages for players instead of spamming a bunch of individual messages. I've seen lots of other plugins do the same. I noticed last night that this ain't working anymore, did they change something?

By not working anymore I mean sometimes it does, sometimes it doesn't, depending on the length of the messages.. Sometimes I'll only see the first line, sometimes nothing at all, sometimes it works as expected.. It looks kinda screwed.

Anyone knows?
