Why does a random tp occur within a sim, and during a walk or flight using the arrow keys or movement icons. I have an alt for which this has never occured and but seems to be independent of the viewer used. Currently using Phoenix. I have been tped through walls and also been stuck insude walls. Many times in a skybox the tp has landed me outside of it. A most annoying result. My assessment based on all the evidence is that some of the info associated with my avi has been somehow corrupted. I would be most grateful to have a permanent solution. PS. The tps are usually 1-10 m in arbitrary directions and accompanied by the wooshing tp sound.
