So I was in Gloombound Mine getting some ebony ore, when a sinkhole fell through to the level of the mine below me. Upon falling into the hole, I fell into infinity for about 5 seconds before landing back inside the mine right next to the sinkhole.

Just thought I'd let you guys know.

So you fell into a sink hole and landed right back where you started from?

Sounds like you fell into a loophole.
