When binding a Wireless Grid to a controller it doesn't check if it's allowed to interact with that block which allows to bypass protection mods like FTBUtilities.

Just did some more testing and it seems to check player interact item instead of block. I only block interactions to blocks to allow the usage of food and similar items.

Not an RS issue. Before ItemNetworkItem#onItemUse is called on my mod, Forge calls the player interact event, which FTBUtilities can cancel.
