No... I think the communication between the main server and S2 was still 'up'. Constantly reporting 35 drivers online. While the actual communication between the drivers, local on the server came in some sort of endless loop.
Dunno, LFS still has some rare weird bugs, related to communication. There is room for improvement, let me put it that way.
But it's rare, so not very serious. I'd rather see the spectate-on-lag blockade being fixed
Has all got to do with not handling communication parallel. Probably (hopefully) Scawen has a complete new netcode laying around. People complained about various issues regarding communication already during the last patch update but Scawen choosed to ignore those.
