I’ve been trying to build on the water at Riversend all morning and ran into this glitch:
It’s kind of hard to tell but after I placed the columns I could not move. I could be wrong but it seems that I was able to move again after I selected another building piece. I’ve been up since last night so I don’t remember whether I couldn’t move if I did not run out of the building piece I was placing.
I play single-player without any mods.
