In vehicules, you can take the items in cargo only if you or one of your teammates has been in the driver's seat.
I will keep adding players from my friends to see the limits of running Ravage with TADST and provide here some feedbacks. Cleanup script is running, and the atmospheric module options are all on. We are playing with TADST on my computer (i7/GTX980/16Go Ram) and a shitty internet connection (standard french connexion type).The zombie are set to 20 zed/player, max to 100 Zed, sun factor on (but no lag seen on night times). For information, we were 5 players with no lags, only some rollback when we were in a vehicule but really minor issues.
