Today is a good day for the for the game Rainbow Six Siege as they have just surpassed the concurrent players' record for the game. This has to do with the release of Operation Chimera and the new Co-Op mode Operation Outbreak. The game reached a peak concurrent player count of 176,856 on Steam today, smashing its previous best on the steam charts website.
Unfortunately, not everything is going well for the game as there is a hefty amount of criticism going around
Players are upset about the lack of refunds for weapon attachments and operators, as mentioned above. If you spent a lot of money unlocking all those operators a month ago then tough luck because you're not getting it back.
The update has come with a few bugs, too, which Ubisoft has detailed in a Reddit thread. They include some players not receiving four free Outbreak packs (which everyone was meant to) and "intermittent disconnections". I myself did not get the 4 free packs from Ubisoft and fear I would considering they won't refund the renown for base operators.
