Avatar moving by himself

While in the new city by the ocean, I entered one of the small homes to place some items inside. After placing several items I then dropped a blacksmith crafting table. Once I did this my character began too slowly drift towards the direction of the ocean. I wasn't able to get a map location as the beta then went to a black screen and only had inventory available. I could not reproduce again as of this writing.

 

A quick update, I was able to reproduce it 100 percent inside the Edleman benefactor Village house. Once I dropped the Blacksmith Crafting Table, my character begin to glide like ice inside the home. I tried to pickup the crafting table and all that happened is it just kept reproducing the crafting table inside my backpack. I then went to next house and the gliding issue was still present, at this point my graphics became somewhat unstable and choppy. I am running a Evga Gtx 770 with a i5 2500 and 16gb of ram.
