I think I may have found a potential fix for this. The primaryMagazine attribute is meant to reference an entity of type 'BaseProjectile', but it looks like AttachedWeapon for AutoTurrets returns an entity of type 'HeldEntity' instead, which may have been changed during the last update. Fortunately there is another method, 'GetAttachedWeapon()', which returns the desired 'BaseProjectile' entity. Simply updating the references should fix this issue.
In layman's terms, find the instances of "AttachedWeapon" in TurretConfig.cs, and change them to "GetAttachedWeapon()". There should be 2 cases where this occurs, both within the "CheckAutoTurretAmmo" method, at lines 467 and 474.
The resulting method should look like this:
private void CheckAutoTurretAmmo(AutoTurret turret)
{
if (!_infiniteAmmo) return;
if (!permission.UserHasPermission(turret.OwnerID.ToString(), "turretconfig.infiniteammo")) return;
var items = new List<Item>();
var projectile = turret.GetAttachedWeapon().primaryMagazine.ammoType.GetComponent<ItemModProjectile>();
turret.inventory.FindAmmo(items, projectile.ammoType);
var total = items.Sum(x => x.amount);
if (total < 1)
{
turret.inventory.AddItem(turret.GetAttachedWeapon().primaryMagazine.ammoType, 1);
}
}
