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.

They likely meant that it didnt show you selectibg rhe track or whatever just before it?

No, we meant the loading screen AFTER the race.

Did it show anything after the loading screen?

It does show if you're using the mod loader, yes.

I meant did the video show anything after the loading screen?

The loading screen at the start doesn't show the mod loader, only the one when you're exiting your run. It's even written in the runs we specifically want the loading screen that is after finishing a race that shows the mod loader list. His video only had the one at the start.
