Those are weird bugs, heartburn doesn't have a sfx on it yet. Alot of those don't occur on my end but I can try to figure it out.
will fix the gore effects
Did a quick test and found a solution. Apparently, the install had bugged on my end. Re-downloading the file and reinstalling the game fixed the issues with the clash sounds playing every time. Only partly fixed the problem I reported with the phoenix fire attack being unavailable in training area though. (posting more info on that on the update page)
