Sadly I don’t have a video or a picture of the drop so this stands only on my words .
Recently I read the patchnotes and was eager to see and test the new weapon / tyrant , so I started to clear rivals from bottom map to the top . but when I was in Norra saltholmen region , a tier 3 prototype rival harvester dropped the experimental meusser . Im glad that I got it super early but a bug must be gone .
Can’t really tell what conditions were met to get this bug but my best guess Is that some code got fumbled and it bypassed the restrictions . Hope this gets fixed for future and current players .
