oRA2 currently sends an RN message when certain buffs are gained and lost, however it doesn't send a message when the buff is refreshed i.e. cast again. This results in incorrect "buff time remianing" information for addons which use this information. CTRA does broadcast when buffs are refreshed.
Please review the fix here:
