The recent 2.0 update to Rainbow Six: Siege has players howling in frustration and Ubisoft scrambling to fix some of the problems the patch has caused. Those problems include barricades that become invisible and continue to block players after being destroyed, melee attacks that don't register as hits, and wall clipping.
Players on reddit's game page have posted a long list of issues with the patch. The most infamous is the "Black Jesus" bug in which player models can sometimes glitch into a "T-pose" that appears completely black, as seen above. Other confirmed bugs include head hitboxes not reflecting the actual target area, barricades refusing to be destroyed, players swinging through a wall when trying to rappel, and player avatars facing the wrong way while moving.
Ubisoft has acknowledged the bugs and have posted a thread in the official forums detailing what the studio is working on, the progress on each issue, and what the 2.1 patch will include. All of the info is updated over time reflecting progress on the update.
According to Ubisoft, the 2.1 update will be available sometime in mid-February. Rainbow Six: Siege was released back on the 1st December 2015.
