Withdrawal shares gone missing

[slundqui]

Somewhere, redeeming withdrawal shares is getting lost in the pipeline. The database has captured transactions for that call, and Jonny has stated that his bot indeed redeemed withdrawal shares. However, the WalletDelta table didn't capture any deltas from withdrawal shares. Additionally, pool info is reporting that withdrawalSharesReadyToWithdraw has been 0 for the entirety of the competition.
