There was a recent update to Rehydrated and while I'm not entirely sure what it did, I just recently beat my pb I set yesterday, but my revision number is now different from before and isn't an option yet. My new revision number is 603519 if one of the verifiers can fix this so I can submit my new run.

Not sure if you've seen yet but the revision number was added at some point earlier so you should be good to submit now
