Ive got an item that seems to bypass Mytown's protection field. Its the force Manipulator from Modular force field systems [MFFS]
You place the blocks you want to send to a coordinate location ontop of the block. They get sent to that area afterwords, Seemingly breaching the town protection.
Tested this on Direwolf20 Version 1.0.21 mc V.1.6.4
My-town Version: MyTown-1.6.1.16
[MFFS] Version: Modular-Force-Field-System-3.6.2.35-core
