Here's my detour. The reflections are being found, selectedObjects is correctly being set to a Verse.WindowStack.
I'm getting a crash when objList tries to AddRange selectedObjects due to an access violation. This seems odd to me as before that line I have already interacted with both objList and selectedObjects. I guess the actual contents of selectedObjects are the problem? Is it actually possible to interact with an internal class or is this fruitless? Thanks.

Injecting this detour with RawCode's TryDetourFromTo:

I've created a ThingComp that overrides CompGetGizmosExtra() to add a "charges remaining" gizmo to a weapon. The gizmo is displayed when I select the item on the ground, but it doesn't display when the item is equipped by a drafted pawn.

How do I get it to show up?
