Refunded passive skill tree resets (After relogin?)

Bug Report ID: #1887769014

My passive skill tree occasionally reverts to a state that I did change quite early in the beginning. I already respecced the same thing 3 or 4 times, but it is reset again. The tree will comply for a while, and at some point when I check the tree again, it is in the old state again.

How to achieve:
Have a travel node that is connected by two paths. Choose one path and carry on skilling your passives. At some point, respec two nodes to instead switch to the other path, and respec the old path point to put back in the respecced ones.
The tree complies for a moment. But at some later stage, the tree will be randomly set back.
