Maps

[runic stone]

ensure those maps are in the .map format. once you have placed the map in the custom folder, you need to load the map by typing in the lobby chat /loadmap filename or restarting your client

once you have loaded the map, select the Standard game mode, and the map will show up there

No just .map

[runic stone]

nope

it needs to be .map, you can just rename it from .yrm to .map
