Probably, you synced with bad nodes that are still running old version. Pls stop daemon, delete file
p2pstate.bin
at directory
C:\ProgramData\sumokoin
and restart it. Maybe you'll have to delete
Imdb
folder too to resync
Yep... nothing wrong with the code... I was just being a doofus (after taking a minute or two trying to find where the blasted p2pstate.bin file might be in Ubuntu and why I could open the log file in the earlier iteration of Sumo but not the current one... it dawned on me that I'd opened up the old version and started syncing that...).

Thanks though
