you can try with -zapwallettxes command line arguments (not console command)
Should this be used when starting the wallet? If so, will the missing wallet Tx's disappear? I ask because atm they are the only evidence that I've sent the coins to the Poloniex address & if I lose them I won't be able to prove that I actually sent them (even though I do have a printed copy of them).
You could try deletetransaction in console
This command gave me a "method not known" error - but the command "abandontransaction [TxID] seemed to work & all 15 payments are now listed in
red, but so far only about 1200 HUC has returned to my available balance & I have no way of knowing which one of the missing payments they came from - or is there a way to find out?
As a test, I sent 20HUC to a different wallet that I control & it worked fine - I then sent another 20HUC to the same Poloniex address as before, which also worked fine - so I'm still at a loss as to why it didn't work before or how to get the missing 4980HUC back.
I didn't yet try the "salvagewallet" command as I figured it was a last resort type of option - do you think this would help my cause?
Thanks for all the input guys - I do appreciate it.
