Lighting needs to be rebuilt immediately after lighting has been rebuilt

I somehow managed to created a phenomenon with one of my blueprints actors. If I drag 10 blueprints of this particular blueprint into the main perspective viewport, customize the blueprints slightly, rebuild lighting… then there’s a chance that 2-5 of them will bug me to rebuild the lighting again.

I’ve been trying to track down the problem but I’m just not sure what it could be. I’m primarily using “instanced mesh components” and the mobility settings are definitely set to “static”… it seems to be mostly random when this happens.

Does anybody have a clue as to what might possibly be causing this? I’ve done like a million things to this blueprint so I can’t exactly give a step by step process to recreate the bug. This seems to be the only offending blueprint and I’m looking for clues as to what the culprit might be.

Are the assists your moving have something that is effected by static light? Or effects the world like casting static shadows it interpret it as needing a rebuild
