Begin Overlap does not work in 1 specific blueprint

As the title states, I have added a box collision to a new blueprint I’m making. Lets call this blueprint A

Sadly, for whatever reason begin overlap does not trigger, at all.

I looked at an already existing blueprint with the box collision at exactly the same scale and everything with the same level of hierarchy (right under the defaultsceneroot) and it was still triggering begin overlap. Lets call this blueprint B

I’ve spent the past half hour simply AB testing every possible thing. Collision settings of the box collision, the defaultsceneroot and the actor itself. Checking activation and ticking, I even started adding components to Blueprint A that it doesn’t need simply because they are in Blueprint B.

I have double checked every setting for the collision, they are the exact same.

And yet. Blueprint A does not trigger begin overlap, Blueprint B does.
What the hell is going on, and how do I fix this?

We are using Unreal engine 5.4.4

Additional things that I have checked:
Location in folder structure (they are both in the exact same folder)
Replication (all the same)

The only additional difference between these 2 blueprints I have found is that component auto-activation also does not function in blueprint A for whatever godforsaken reason.

Edit: I restarted the editor and it all works now, I am going to throw my laptop out of my window.
