Not sure if this has been reported yet, I couldn't find it here on the bug forum.
New world running on beta (453468), had this issue occur to other players before it happened to me.
When trying to long press to do an action (mine a boulder or cut down a tree), the character would slide across the map to some random location to try and perform some random (?) action on the new spot.
When this happened to me I managed to record a clip - you can see on the video I used the space bar to chop the birchnut tree, then missed it with the mouse click and when I then long pressed on the tree the character slid all the way to camp to try and do something at the crockpot.
I didn't try it but other players went back to the tree (or boulder or whatever object caused it) and the exact same thing happened, 2 or 3 times until they managed to cut/mine the tree/boulder.
I've attached my client log. This happened to me about 2 hours into the game but the log doesn't seem to record anything useful related to the glitch.
Cut a series of trees or mine a series of boulders using long press action and eventually this glitch might occur.
