Sentry processing transactions but not errors

After a recent upgrade and filesystem switch, I cleared out our sourcemap and file tables in postgres to start fresh. Since then, Sentry has not processed any new events

All of the containers report healthy, no logs to indicate otherwise. Kafka is on the latest partition
etc. The queue processors seem to be constantly reading events:

2021-05-06 04:29:52,844 Completed processing <Batch: 11 messages, open for 1.23 seconds>.

Curiously, I am still receiving email alerts notifying me of new issues coming in - indicating that post process forwarder is working fine.

Latest OnPrem 21.4.1

Solves this issue!
