Botania Microblocks Vanished

[SilverKytten]

I recently added Ancient Trees, Kore Sample, Decocraft, Custom NPC, and ArchitectureCraft to my server and, after doing so, all Botania-related microblocks seem to be completely gone from the game.

I'm honestly at a loss as to what has happened - I haven't changed any configs around, the only changes that have been made are adding the above mods -- Two of which, Decocraft and Custom NPC, had been on the server previously, with no issues.

Is there a way I can re-add the blocks into the game? Do you have any idea what's going on?
