Hello Lou,
about first issue, your HQ buildings, especially Manufacturing, are repaired and in pristine condition (no damage bar displayed)?
2nd, there were reports lately that weather got out of sync on (some) race simulations. It hopefully should be fixed by now, if not some more feedback (race ID, track) would be appreciated.
About XP, that one needs looking into yet. However I'd expect 322 XP according to the latest formula I'm aware of, if no XP booster active, for races in your league. So it looks like it's rather handing out too much than not enough XP, despite showing even more.
