Medoria messed up some things by adding Lunia: to all links. So this went wrong for images links: Lunia:Image:Name in place of the correct Image:LU_Name. Now its fixed only for monsters. Also it went frong for categories
Instead of Category:LU_Name now it is Lunia:Category:Name
I hope there are not many like these...
Also the names of the images seem to be different from the name of the monster. To keep the wiki consistent, the correct image name will be Very_Long_Monster_Name not VeryLongMonsterName.
Before, by clicking the red link he created a new page
Now its fixed for the monster template.
