Yeah, that I can't explain particularly. I've been trying to figure out why the hell it's been paying like that. The wallet software only has one or two addresses, yet somehow it has temporary addresses for every payment it makes - every payment has a seperate transaction. The issue doesn't exist for other wallets, they pay all their coins on a single transaction. SIGT however does not, or at least just started doing that when the wallet first went into negative balance.

IMO the SIGT coin has been nothing but trouble... no end of weird shit happening with the wallet/blockchain.
