On the contrary, I said that we did not know about the bug when the patch went live.
But the truth is that you probably did knew about it. Or maybe that depends on what you mean when you say "we". If you by "we" mean the devs and community managers then it might be true, but if you by "we" mean Blizzard as a whole, well, then I have a hard time believing that you didn't knew about it. It was reported, the report was read (I would assume) by someone hired at Blizzard and it would be fair to assume that the person reading the report (or more likely the persons reading the reports) understands the english language.
So you as a person might not have known, but you as company most likely did (and if you still claim that you didn't I would question why you don't read and/or can't understand bug reports).
So basicly the question is what you guys mean when you say "we". Only the devs? Only the devs and the community team? The whole company including the support guys and QA? Because I find it strange that you admit that the bug was reported buring 1.07 PTR yet at the same time you claim that you didn't know about it. There are only two logical conclusions to make: either you didn't read the 1.07 reports until now (and then you truthfully didn't know about it) or those reports were read, but by people that aren't included in the group you are refering to when you say "we didn't know about it".
