I have uploaded more than 100 sgf file from kgs. Unfortunately after uploading i noticed who won in a game isnt shown here and comment of red marked move disappeared . While doing a review the stones also changed and showed strange numbers on the board. Guess it will be fixed soon .
Yuck… yeah there are several SGF issues in the backlog, I’ll be getting to them soon here. Once I get them fixed up it should start showing up right for you, you wont have to re-upload them or anything.
