you have been warned:
as of 6:45pm EST jan 7th, i have confirmed through a series of unfortunate events that portal guns are just slightly bugged.
when you make a portal, it is a good idea to make the portal several blocks above ground or u might end up well.... below ground
case in point, i made a portal to my nether portal, and instead of coming out above my lava lake, i came out under the lake losing all my stuff.. not fun to say the least.
so BEWARE!!! portal guns are bugged!!!!!!
