So without proof any argument is totally invalidated? People lie in most situations to save face, even for small things let alone as a company with a publishing giant they have a multi million dollar contract with (and it's investors to keep happy) breathing down your neck. The push mechanic is something they wouldn't have been able to notice easily, if at all while playing the encounter properly. The timestream teleports on the other hand happen numerous times an encounter, it surely would have been noticed there's a consistent pattern to it rather than being random throughout the test phase. Though, even if they did miss it themselves, the community worked this out within the first few days of the raid unlocking with the countless steamers and YouTube how to videos yet there was never any mention of it being a bug until now, it's a bit too convenient. If this was a new discovery and they'd acknowledged it sooner I'd believe it, but it just seems like a rubbish excuse to mask a last ditch effort to increase the difficulty because it's easier than they had originally anticipated. As I said before, even if it is a bug it really isn't game breaking like the 1 min atheon push and templar pushing. They are eating up dev time which could be used much more effectively at this point making sure the new content doesn't have similar flaws. Every game has bugs, some are left though because they aren't a valuable use of dev time to bother fixing, just aren't that bad or give people a laugh. Some bugs even stay just because they actually make the games a little more enjoyable with their unintentional consequences, the bugged knife in battlefield 2142 was one of my (and a lot of other people within the communities) favourite things, made for epic knife fights.
