Simple fix: Have your ability use a csay as well.

The problem is, bash already has a csay running if you get bashed.  So when you buy the anti freeze and get bashed by say human, the csay message from humans bash says you're bashed for 3 secs, and "es es_xtell event_var(userid) #Multi #GreenAnti Freeze : #LightgreenYou are unfrozen now!" both show on screen.  I know there's a way to make it so humans bash won't say it if you bought the anti freeze and it's activated, but I don't know how to do that.

This shopitem is working now, but it displays both messages.
