Editor starts trying to bake lighting on play

I have a project with no baked lightmaps (it looks better like that), and auto-bake turned off in the Lighting menu. However, whenever I press play, a bar appears at the bottom-right that says 'baking paused in play mode', and proceeds to stay at around 1% for the rest of the session. It doesn't visually interfere with my lighting, but has weird side-effects like turning all of my reflection probes black until I quit and reload the project.

Other information: Using Unity 2018.2.6f1, and using the Lightweight Render Pipeline and OpenVR

 

Edit: Seems to have to do with having a realtime reflection-probe, but I'm not entirely sure
