Flashlights are attached to weapons for a very good reason - they will collide with the weapon. Weapons aren’t drawn on a separate layer like in older game engines, they are rendered in the world with everything else. By attaching the flashlight to the gun, it keeps it from clipping with the gun, basically.
What needs to happen for some weapons we can easily ignore this and have it use the default offset and it should be fine. The fishing rod just needs to use the default offset. Currently the fishing rod offset is right on the hook.
