[Tekkit Classic] Plugin warns the admin when players try to mine None-vanilla blocks (E.G. Rubber tree)

[Tobias00001]

Hello AntiCheat devs.
I started a Tekkit classic server that uses your plugin and I noticed that players can't break any natural blocks that are not normal vanilla blocks. The plugin counts it as ''Cheat'' maybe because it does not know the blockIDs.
Can you try to fix that?
