for some reason we cant remove this block in anyway

Whoever made that elevator needs to shift right click it with a stick, or I think any player in creative mode

any player in creative isnt working we tried that but will try the shift click method and report back :D

if you have other mods, you might need a wrench if thut found it in FML start ;)
i needed to make myself a wrench from extra utilities, then sneak right clicking just put the block to solid... you remove this one block, and recreate the elevator process :) you should be golden then :)

if a wrench worked, then a stick should work as well, it is supposed to check wrenches and sticks

You are absolutely right thut :D my bad, yep i can also "unmount" the elevator using regular stick ;)

Hope OP figured it out then ^_^
