BP actor object has a weird moving animation

my object I have created in a BP actor class moves weirdly, and I can’t explain what happens. To see an example here is a video from it:

in the video you can see, that the actor is moving a little bit, what causes, that the tree trunk does not look as the same as the top of the tree, since it seems that the top is static…

I already tried almost every option you have to edit the objects, but I haven’t found the solution yet.

If someone knows a fix, it would be great. Have a nice day!

i cannot see any movement in that video

Got fixed it! the material was the problem that gave a new animation to it.
