Sorry about the delay, I've be waiting until I've found and resolved the issue so I can do a one time correction. Unfortunately it happened again last night so now I've put in code to attempt to detect the issue when it happens and autocorrect. This means going forward the bug, while still existant, won't have an effect. Now that that's done I'll revisit the uncorrected blocks and do a fixup. What I'll probably end up doing is a btc payment to all the affected accounts based on the affect the extra blocks had.
