Describe the feature request

can you update the plugin to 1.21.4 please it is outdated and also can there be a command to rebuild the inside of the tardis

Describe alternatives you've considered

or you can make it where the items for rooms drop as a item when broken because it turns into an item frame when broken

The 1.21.4 update has been in progress since mid-November - there are some big changes to Minecraft items in this version which TARDIS relies on heavily.
There is a working branch for 1.21.4 - feel free to compile the plugin yourself.
Otherwise, please be patient.
