I wont go into details in here how to exploit manual reloading, since i dont want to give pepople instructions on how to exploit in raids.
Con already removed reloading during raids by pressing the r-key. Now you have to click the weapon icon to manually reload your weapon.
But people still manage to abuse the reload function during raids. I know this, cause i have been told by someone how he raids my compound and a lot of others.
So please just get rid of reload once and for all during raids. It is really not needed since the AI already automatically reloads your weapons when your ammo is low and your survivors are idle.
Its far more important to have fair raids, than that little bit of comfort to now and then reload your weapon manually to have a full magazine.
