@ F 50 - There seem to be 3 posts that are very similar between the two threads and that could potentially be seen as copies of each other. The problem is that while your thread was originally posted before their thread, both threads have also since been edited. And on 2 of the 3 posts that look identical, your edit was made after the edit on the other thread. That makes it impossible for Forum Moderators to be able to tell who posted what first, so there is very little that we are able to do in this situation.
I recommend that you contact the other thread author in game and see if you can resolve the situation together.
