I'm switching between two orgs, A & B, and when generating an offline symbol table for org A, I see all of the object fields I would expect to see. When generating an offline symbol table for org B, I'm missing a single field in one custom object.
This appears to be triggering an "An unknown error has occurred" message when trying to save an Apex Class referencing that object and field.
I've deleted the offline symbol table in org B and recreated, and it's still missing the field in question. I've confirmed that the field exists on the object in org B and that the object and field definitions are the same between orgs A & B.
What could be causing this field to be missing from my offline symbol table?
