I am not sure if this is an essentialsx issue or a commandhelper, but after switching to essentialsx from regular essentials modifying the chat event using commandhelper no longer seems to be working

This little commandhelper script would put a heart before your username: http://pastebin.com/N4tvGFBr while still keeping all the essentials features such nickname, chat radius etc

This no longer works, perhaps its the event priority?

Are you using essentialsxchat? We haven't modified that project at all other than reformatting it.

yes, I talked to the people from commandhelper they said it was most likely the event was set at the same priority

alright :/ but it only broke after switching from the old essentials to essentialsx

Ess chat runs at 3 different priorities for different things. I'd have them look at it.
