Hello,
Can't access the support page so I'm posting here, hope that's fine.
Now with the new very cool Task Force 666 PvE event I noticed a bug with the 2x-1x OKP-7 sight and NVGs.
For reference here's a screenshot of the 1x OKP-7 with multicolor NVG:
Now here are the 2x-1x OKP-7:
In the screenshots I used the AK-74 but I tested this with the some of the guns I use and found them all to have this issue.
I also noticed, may or may not be related, that on the loadout screen the 2x-1x OKP-7 sight doesn't render on the gun when looking at the full loadout, renders in the gun customization screen.
Hope this get's fixed, keep working on the amazing game !
