At random times my character just glitches out when I go up high places. I have posted videos to my YouTube channel so you can see them. https://www.youtube.com/channel/UC_Qeavbj1E39TjuYJ-HgAoQ

In this video I was going up the tower and my character started, kind of flying around and eventually fell after I opened exit menu.

Before this video I was at a radio tower and climbed up the top, I had collected a pair of binoculars and my character started to act like it was falling from the tower, after this I was in the building and walked off the steps and then started to see through the floor and everything else that happened during the video.
3rd thing to happen, I was on a radio tower and had climbed off at the first section, I had then moved to my right fell off the side like there were no barriers there. My character died on impact of the ground. I have no video.
