When i am walking/running on a straight wall of block it automatically jumping. As you can see on the video i linked i provided(i can't upload the video here due to your video limit size). even though i am not using jump button it really automatically jumping with or without using my gamepad. this is a nuisance specially when im in a hurry going inside in my shelter with a door it jumps and jumps hard to get in my shelter it pisses me off when that happens. please fix this issue.
