After upgrading from ver 13 (not sure exact) to latest (15.4.54), all my multi-currency transfers are wrong, throwing off all my bank balances. Seems that it switched all my transactions to use what was previously the target account value to the originating value.
Something like previously was
USD -50 to IDR +500.000
now shows as
USD -500.000 to IDR 500.000.000.000
Wish I would have saved old installer to revert, but only fix I can see now is to go back and fix all the transfer transactions.
Any other easier way?
