using hidden trapdoor on spatial pylon from Applied Energistics causes a boot to the main menu

[PrismDL]

So I've been experimenting with Spatial Storage, and was trying to make a hidden trapdoor that leads into the power supply area, since it's a bit ugly. I placed a hidden trapdoor on one of the Spatial Pylons, and it immediately kicked me to the main menu. I haven't been able to rejoin without being kicked again, and a friend of mine attempted to go remove it (we play on a small server), and he was also kicked, and is now unable to rejoin. Is there a way to solve this?
