A very smooth way how copyright thieves do their tricks of the trade. 1st they deny you that your work isn't good or just like here, you say "IT'S NOT A BUG". Then they they get your work, re-edit it and claim that it's their own. On this matter, the whitehat proved that there was a bug, then I'm pretty sure you tried to look further into his report and then figured out to identify the issue. Stole the idea from the whitehat and had it fixed.
