When I was testing a quest made on b15 using b16, I encountered the following error. The enemy bombchu came at Link and when it exploded, half the explosion came and after a split-second delay the second half appeared and in the midst of the smoke, I could distinctly see an empty heart container (!). I tried this also with Lvl. 4 Octoroks and a few other bombchus. The explosions occurred the same way as mentioned above except this time showing some other tiles in instead of the smoke.
