Tables Degrading and Losing Data Across Workbooks - Known Issue?

Tables eroding/degrading?

I’ve just noticed a number of tables I’ve created over the past 6 months, with enrichments and automations in them, some pulling from Gong and doing cascaded analysis… some pulling from Hubspot, doing enrichments and feeding back up to Hubspot… … last I checked these had all been solid and chugging along But as of my check-in today, it seems they’ve all degraded and eroded somehow. Some lost all their columns. One of my Hubspot tables that pulls from a distinct list of 855 people has somehow become a 50,000 row table with every person from the Hubspot database (until it hit the 50k limit of course). Our Pro account is in good standing, we have a surplus of credits, so it’s unclear how this could have happened across different workbooks and tables. Is this a known bug?
