@@ -23,6 +23,7 @@ Following bugs are known and worked on:
 * Exits on the outer most right tiles dont work
 * exitUrl in combination wir multiple exits to the same map leads to confusion in starting points.
   exitSceneUrl works instead, but ist deprecated.
+* Loading a tileset twice (with the same name) results in interesting rendering bugs (e.g. missing tiles in WorkAdventure)
 
 ## Limitations
 Instances wont scale indefinetly, please keep that in mind while building maps. From our experience the limit is somewhere around 200 players. Maps for 2k players wont make any sense. Please dont try to build lecture halls. There's no sense in idling in the game while watching talks.
