I have already addressed this previously, though I can't quite find the post:
1. It will be fixed in the next update.
2. Originally when the bug was found, a ticket was sent in asking Debbie if it was OK.
3. It was OKed.
4. If 1, does not work or happen, we are already working on current other fixes, but until then it's allowed.
There's plenty of other glitches as well, OL water glitch, overflow bug, etc that people seem to still abuse, but yet we have to let it slide until it's fixable.
It may be a money abusing glitch, however it's still not as wide spread as say, the buckler/nine tails glitch during the event. Nor would it be gameplay/economy breaking as a certain other MVP glitch that existed a while back. It's 1 Valk, every 2 hours, or some other MVP, every ___ hours, which has a chance of dropping an item. The star glad is also limited to what map he memos. Should it be an unlimited amount, with an unlimited amount of items which are dropped, and can do this to every MVP, yeah.
Had it been like that, heat would have been completely disabled by Debbie IMO.
