Reported, of course.
During OSU, Quicken closed. Always indicative of a crash. I reopened, did OSU. Partway in went to Syncing Bills With the Cloud or similar dialog. After that, Quicken reported 3 credit card accounts had been deleted.
Right or wrong, I tried to restore from yesterday's backup. No change.
Each CC account required something different to restablish. One just allowing biller to reauthorize. Two required adding as if a new biller and linking to exisitng. All seem OK now, but where Elan Financial Serives Online Biller is degraded and still pending in MAC, it WAS working in Windows still. Now is Pending in Windows as well.
No idea what caused all this. Obviously concerning.
Posting as a question in case anyone wants to discuss or anyone has thoiughts why the crash in the first place,
