I see where Quicken posted they found the 'cure' for duplicate transactions and that the system would 'fix it' — this was posted 6/2. For me on 6/3 Quicken went in and wiped out a ton of non-duplicative transactions, thereby effectively blowing up my accounts (I note I did not have the duplicative problem in the first place). Sorry but the timing lines up too well for these two items not to be inter-related.
