I've seen the pit lane limiter warning msg a couple of times since the update. It never pulled me into the pits but I've seen it. Perhaps the final corner at Nurb IIRCApart from Kyalami, Imola and Zolder, have any other tracks got the bug where if you drive too close to the pit wall, it sends you straight to the pitbox?
I know some will think you're going in and the pit limiter notification comes up
