Hello there,
Thank you for your report and the footage.
We understand you have encountered an issue with Citan's Ramparts. Having viewed the provided video, we can imagine the impact this issue could have. For our investigation, could you kindly let us know whether you experience this issue with these barriers outside of the Shooting Range? If you do, and you happen to have footage demonstrating this outside the range, then please share it. We'll then review.
Additionally, when weapons have an anti-barrier effect, they can also penetrate these two stacked barriers (Outbreak Perfected can penetrate them even without an anti-barrier effect, which is very strange).
I completed the weekly campaign mission on Mythic difficulty with my friends today, and this issue still occurs, so it is not limited to the firing range.
