Our track artists have found the potential reason of the issue and it seems like Risto's explanation below is the most accurate one here. We will update the track as soon as possible, within the next hours for sure.
Update: this S/F bug is pretty much tracable to where you cross the line. If i go not from the edge of the track but a little bit to the left then i get problems 0% of the time
And then i started getting same thing with split timers aswell, suddenly some dont work so whole lap doesnt work.
This means the timing gates are just placed poorly on the track. Could be fixed quickly and before the race/ RTTW end if you guys really wanted i think
