God Mode does not seem to work right.

It protects against enemy gunfire, but not against explosions.

I seem to remember another way to get a working God Mode, and will try to find it out again.

I can't use ironsights or scopes on weapons I add and I need to drop and pick up weapons so I can shoot


P.S. No problem with ironsights now but the other one stays

Which function are you using to add weapons? The Weapon System?

Have you added any other addons that might affect the sights?

Also,
Be sure to use Lost Key v72.zulu, it fixes a lot of bugs.

The link for v72.zulu on the BI forums is:

P.S. - try reloading your weapon after giving it.
