Guild Wars 2

Normally, players are removed from a guild puzzle area when the timer runs out and the puzzle is deactivated. However, the removal does not take place if a character is logged out or disconnected while the puzzle is still active, thus allowing the player to return to the area in its inactive state later on. Specifically, the end reward chest is present even in the inactive state and resets daily just like normal jumping puzzle chests.

I noticed this issue in Angvar’s Trove but the other two areas are probably displaying the same behavior. Since it’s infeasible to trigger removal on logout/disconnect, an appropriate fix would be to check during character login whether the area is still active, and redirect the character if necessary.

Maybe an easier solution. Do the same as in Loreclaw expanse. Make the chest room collapse on top off you (killing you if you are there while inactive)
