did have an anti block script running , that was active for first 5 seconds or summat, to give people a chance of getting out of spawn without blocking eachother. Unfortunately with all the steam updates there is a lot of issues with lots of server add-ons, you'll just have to wait till jason reads your post, and hopefully if he gets time mayeb look into it for you.
Sorry i can't be of help, bbut other than that, just run away from people at round start, instead of flocking with the majority
