sorry for almost immediately posting another question, but I just don't know how to fix this, any rocket launcher, grenade launcher, and sticky bomb launcher without preserve_attributes 1 will shoot very slow-moving projectiles that do very little damage. Sticky bomb launchers won't even have any ammo in the clip. is there some critical base attributes that I'm missing?
Turns out you have to put a 1 in front of the damage bonus and projectile speed stats (1.XX) otherwise they will reduce it, I'll leave this here in case there's anyone new that's confused like I was.
