Analysis board for Antichess after the games seems broken - I can't move the pieces like I used to be able to. It does however work for standard games.
Antichess and atomic replay has had some issues and I'm guessing moving on analyse page is disabled until it gets implemented completely. Although three-check has also been affected, might be some issue with check-count.
Currently pieces should be movable in: standard, fromPosition, chess960 and kingOfTheHill
