In the TU16.1 summit, if a player attend a session on a floor lower than player's checkpoint, a player will not receive XP for clearing that floor.
My checkpoint was on the 11th floor.
At this time, the player I was matched with had a checkpoint on the 1st floor.
I completed floors 1st through 10th in this player's session, but did not gain any XP on any of the floors.
There are three actions we players can take to avoid this problem
(1) Players reset their checkpoints before being matched at the Summit.
(2) Players should leave immediately if they are matched with a floor lower than theirs and re-match until they are matched with a player on a floor higher than theirs.
(3) The player stops playing at the Summit.
Is it the intention of your development team to force players to make these choices?
