WEIRD nonsense ocurring with decoy module

[lanc12]

When I remove a Decoy Module with others around it, the decoy module will be removed... but the texture won't. This leads to some wacky Z-fighting between the Decoy Module's former texture, and the Casing.

Also, when you remove the last one, all of the textures disappear.

This is on tis3d-MC1.20.1-forge-1.7.7+354a583, so maybe it's been patched? I dunno.
