Slitherine

I have a couple of challenges of a modded scenarios that I would like to remove.
But I cannot access either of themn(from the my Challenges list).
And for some reason they also show up in the All Games list.
It is the two Burmas

Contact us at support[at]slitherine.co.uk, providing the name of the game, the scenarios names and the usernames of both players.

I think I solved it.
