Just set my times - very happy to see a gr.B rwd event
Going nice and slow without any accidents until on the last stage I was hit by this stupid rare bug that still happens 1.16, which me and other users have reported it on previous versions without CM doing anything about it. So I'll explain it here for anyone that was unfortunate have before without knowing what to do.
Having manual wipers (auto wipers assist disabled) can cause them to perma-stop in the middle of a rain stage without reason or car damage, leaving you blind with water on the windshield until manually turned on again. Then they'll keep going completely off randomly every >15s seconds or so after you repeatedly turn them back on.
It's not the intermittent electric fail on a damaged car where they miss a swipe occasionally, just them going completely off without any user input to do so (and no faulty assigned button input).
The only way to stop this hellish situation is to pause the game right when you see them unexpectedly stop and you go blind, and then enable the auto wipers assist. From then they'll keep working fine until the end of the stage. With some luck, it won't ruin your stage, but your concentration will surelly suffer. You'll lose a "no assists" result on the timetable too.
(Reported once more on their forum *sigh*)
