Well, you didn't really invite dialogue on the subject... You just kinda stated that it seems they run out quickly. You didn't give any more information. Also, this was posted in General Discussion and not in the section for Bugs.
I'm sorry, I assumed(mistake on my part I guess) I posted a question that would by design invite dialog. The information is that the rum boosts are expiring quite quickly now.("Anyone notice how quickly the RB expires now") I posted it in the general section, simply because with the ongoing and continuous changes Kano makes to the game, the thought of it being a "bug" never crossed my mind, I just wrote it off to Kano making yet another stupid, and player un-friendly change.

Thank you for bringing this to our attention. Earlier this evening we pushed out a fix for this issue. Your attack boost will now last for the full time.
