A video worth thousand words: https://www.bilibili.com/video/BV17T4y1M7BR In short: The leading car lagged, and teleported into the car behind, and sending the poor driver into orbit. (Note: the leading car was not damaged, and won the race eventually) This problem started to appear since a version 3-4 months ago. This is the third time it happened in our local endurance league(6 hour race). It's a very serious bug. Hope it can be fixed.
