On the DMU Public server, when i do the command /accept-items it says i have nothing from the dmu store even though i purchased some tardis exteriors in the past version of the mod.

Your Skin is Done!

like my new tardis interior.

The name linked with your SWD account is just DalekDude. You can see it on the left of your profile. I'll update this for you in a bit

I've just checked your user info in the database and I can't seem to find anyone by the name of DalekDude, are you sure this is the correct Minecraft account you're using to play on DMU?

Hello, on the server you need to type /accept-items, a chest will be placed at your feet with the item inside of it
Hope this helps
