I have just downloaded from lfsworld the attached hotlap, and when the car starts the pitstop (around lap 6), lfs stops playing the replay, saying replay OOS error

Replay is done with W0

It´s happends too with wr on so1r-mrt..

iirc pitstops and resets will cause the hl to go oos
afaik theres nothing that could be done about it after changing the code as much as it was for patch x
the obious solution would be to have a copy of w around for the rare hotlap in which the driver resets for whatever reason

Didn't know that :/

I had read that there has been some oos errors with spr on test patches, but i thought were totally solved.

Luckily i have done backups of U20, V, and W versions
