My main character got stuck in a cliff while walking, then started glitching (moving up and down really fast) and was not be able to get out of terrain and continue walking. I have reproduced the bug once. Screen shoots http://imgur.com/a/taIBT.

second minor bug: target for interrogation was on a cliff, I have grabbed him with E, then after pressing B to start interrogating the target the player char would just release the target. It happened several times before I after grabbing the target I dragged him down from the cliff and then interrogation button worked fine.
[wrong game this post was about Ghost Recon Wildlands.]
