Hello,
I think u should disable gravity guns in rp server becouse like if i be a gundealer i mut make the place secure and i cant weld so i can only freeze but when you freeze if they make left click with gravity guns it will unfreeze and they can steal your guns but if u disable gravity guns people cant sell guns so i think you should give weld ability to all players.

I think this has been fixed now.
Thank you for your report.
