You may wish to contact an admin staff in regards to why your AV is gone, as this is something above the moderation staff power.
It may have something to do with the fact that your IP address shows that you are currently in Alabama. It may or may not, are you a US citizen? Or are you currently working in the US this week? I could understand the removal of your AV as you would no longer require it if you were a US citizen trying to sell a gun from the US to someone in Canada.
Contact an admin staff they will have the answers you are looking for.
