Guys, I used a nether portal yesterday that I constructed in a cavern I had made somewhere around y: 10, x: -50 somthing, and z: 750 something. Little did I know that there was a tower, protected by mods, that had a nether portal where I am teleported whenever I try to escape the nether, leaving me no where to go but back in the portal. If someone could unprotect the tower or fix the staircase or the ladder that lead out that would be great.
The tower also has red and dark grey wool for a floor, if that helps any.
Problem fixed, thanks to Dense
