Yes, balance only goes up after pool finds a block.

I double checked, and the pool hasnt found one since 7:30 AM or so.  Today, the issue was the database layer is now running in a different language; it kept going up and down and causing the wallets to solo mine (so they probably found plenty of blocks solo today), but anyway, I found the problem; this is something new; Im deploying the fix now - it just started today on the sleek version of the pool.
