I just clicked the randomize button for the first time since site switched to clam
It's strange that my first bet started at the 2nd nounce.

We recently hired a new employee, told him we would pay him a share of the profits, and immediately gave him commit access to the source code...

Just kidding.
I didn't reset seeds when launching for CLAM. You have the same client and server seed as you had before. Your rolls carried on exactly where you left off with BTC. Your last bet for BTC had nonce 1, so your first bet for CLAM had nonce 2.
There's only one user whose seeds I did randomize before launching for CLAM, and that's because I told him how long his current losing streak would have ended up being. He could have used that information to win huge bets, and so I reset his seeds.
I'm searching old JD logs to try to find your last bet there, but it's taking too long, so I'll just post this for now and update later with details.
Edit: I found it. You only made one bet on JD on that account:
2013-09-23 00:49:55 bet #136404735: 40 BTC @ 98% hi: lucky:388747 profit:0.40816320 n:1
2014-12-12 06:00:43 bet #xxxxxx: 17 CLAM @ 96.5% hi: lucky:883579 profit:0.44041458 n:2
So that's where the nonce=1 bet rolling 38.8747 happened...
