I uploaded a run for 2.11 RWD Nav Base REV and it was rejected for “no loading screen” even though the loading screen was displayed at the start of the run.

Ah no worries :)

Yeah that's something that is pretty obvious, however there was a run in Navaro Base A RWD (which has now been removed, credit to you mods) which was ran with an AWD Rolla ZR and it stood for a while.

I was just curious as to if there was a way that something as easy to overlook like that could be avoided :)

Does anyone know a way we could 100% be certain of whether a run was done in RWD or AWD. Obviously some cars have only 1 option, however some have both and can be abused in such ways. For example, I could use the Last Prince which is RWD but put on the Racing mod and it's then AWD. If I was to complete a run, get the WR (or any placing) and then just claim that it was the Ultimate mod I don't see how anyone could prove me wrong.

I thought recording the loading screen before the race would be a good idea as it displays the current mod type being used in the top right but that could easily be spliced. As I see it, it would be the best way as opposed to just recording replays which don't display it. Which further asks the question, should recordings that don't include the mod displayed before the race be accepted?

Does anyone else have a fool proof idea? Thanks

I disagree with this. Even though it's a bit cheesy, it's part of the strategy. The main idea behind any speedrun is to get from point A to point B in the fastest time possible in any way.

Not sure if you've found it out yet but its adhesion. The limit for tyre adhesion used to be 150 but now maxes at 120.

The current world record "Navaro Base A: After VER 2.7.1 (120ADH) - Rear-Wheel drive (RWD) in 0m 59s 619ms by Shinji-Inui" seems to be illegitimate.

It's in the Rear Wheel Drive category but seems to be an All Wheel Drive Rolla ZR.
