Describe the bug

To clarify, I am not using the TARDIS Resource Pack. So the textures for the TARDIS blocks and GUIs should be the default Minecraft textures.

I am not using any other plugins. Just the TARDIS plugin on a freshly installed server.

MC version: 1.21.4
I tested with Spigot and Purpur servers.

To Reproduce

1. Fresh install

There is no error messages.

Not sure why you'd want to use the plugin without the resource pack, but your choice.
The plugin now uses Minecraft custom item models, if the model is unavailable (i.e. no resource pack) you'll get the missing texture / model black and purple.
If you want a more vanilla style TARDIS resource pack try FuzzyLeo's fork - https://github.com/FuzzyLeo/TARDIS-Resource-Pack

I actually enjoy using the texture pack, but I'm trying to set it up in ItemsAdder and I'm having trouble getting it to set up, so I decided to leave it with the sound pack.

I'll look into ItemsAdder when I get time - I'm presuming you want to merge resource packs?

Hmm, might be a bit hard as I have no need to buy ItemsAdder...
