Why is this bad?

-> reloading the page means a) you lose your checkpoint b) you get returned to the start c) the game resets the map to default zoom level and d) you have to wait a second for it to finish, which is annoying

When trying to return to spawn, issue a) and c) are particularly frustrating, a) because you often set a checkpoint to be able to return to the place you were at before returning to spawn and c) because when youre returning to spawn trying to find the exact pinpoint after finding out the road youre on or the town youre in means youll have to zoom all the way back in and, if you havent placed your guess marker on the map already, might even have to search for the exact place you were looking at again.

When trying to return to a checkpoint, issues a) and b) are particularly frustrating, because that exact combination not only renders your checkpoint useless, but also returns you to spawn, losing all progress you had made when moving around. As I will explain in the next section, this bug primarily happens after moving quite a distance away, so having to walk all the way to the point you were at before can be extremely annoying.

How to reproduce this bug?

I am honestly not quite sure, losing your checkpoint seems to occur significantly more common after moving around for a long distance (time does not seem to affect this behaviour and this might be observation bias as i return to checkpoints more commonly in rounds where i walked for a long time). The page reloading after returning to spawn is a round-specific behaviour, which means the bug will ,when talking about a specific round either always happen or never happen. If in a live challenge multiplayer game, when either of these bugs happen to one player, they will also happen to the other player. (I have only encountered this in live challenge mode because I usually dont play duels, but im sure it exists there as well, both in party mode and in competitive duels)
