World Block Importer from Integrated Dynamics not working. At all.

FTB Chunks implementation?

Nevermind, I'm stupid.

For anyone having this problem, check on the FTB Chunks config by clicking on the team icon on the top left of the screen, get to the config and "Allow all fake players".

If that doesn't work, open the FTBchunks config on your server properties folder and look for "fake_players: "check"". Should be in the 27th line. Change the "check" to "allow". It'll work fine after that.
