When I chopped down this Jungle tree, the fully grown tree appeared to stay intact. The act of chopping it down still dropped its logs as if it were done successfully.
The "ghost tree" that was left could be examined, and when I did so, Wilson said the lines for a tree stump. I was able to dig up the ghost tree as if it were a tree stump.
The videos describe the issue better than I can.
Video 1 shows the bug happening 1 minute and 30 seconds in.
Video 2 shows me digging up the "ghost tree" with a shovel 35 seconds in.
As for why the videos show more than just the bug, I wanted to make sure that the developers are able to see what circumstances led up to this bug. I hope this helps track down the cause.
