Important information for floofs that hasn't read/looked around the site that muchies:
Log into the yellow box next to the banner. It lets you reset any characters position on your account, just go into "Reset character" and it will be self explanatory I believe.
When a character get stuck in a map, it's due to the map process itself not working as it should, which means anyone on the whole of FH that tries to connect to the same map will face the same fate. This is a thing that can happen quite often, especially for more used custom maps since they keep getting started as soon as players join it, or shut down after players left it. Going up and down constantly increases chances of a map getting stuck. In order for it to work again it usually requires a whole server restart which we do once in a while.
Hope this helps.
