We ran into a small arithmetic bug with how liquidations work (using the requested liquidation size from the call message instead of the actual size that can be liquidated).
This led to some bad state in 2 accounts and the borrow lend USDC pool. For now that’s prevented users from creating new accounts.
We’ve patched the bug, and are deploying some fixes to hopefully rollback the problematic state today, so expect a few hours of downtime on the rollup.
