Not long ago me and my friend saw a weird thing. Sometimes our weapons would randomly change into their counter strike source counterparts (they loose all their attachments and and change into low poly versions like AWT-40 changes into AWP). We didnt know what was causing the issue, at first we thought it may be caused by the attachment addons. However, today we finally found out that the issue is caused by distance from the center of the map. There is a invisible border, (around 70m from the border of the map but it may vary) after crossing which weapons change into their CS versions. If anyone else has a similar issue or knows how to fix it please let me know.
