Lights changing brightness upon enable/disable. Also occurs with ctrl+z sometimes.

For some reason, the lights in my marmoset scene have started to change completely upon clicking the eye button to enable and disable them from view. I started to notice this when I was changing settings and then I would ctrl+z it to undo and something somewhere else would bloom with brightness for no reason. 

When I click the eye buttons, the settings of the lights themselves are not changing but they are creating more brightness which doesn't make any sense. I thought this might be a viewer problem and so I rendered out some images and the changes are present in those as well.

You can see in the attached gif that clicking the eye for the folder of lights will change and then doing the same to individual lights will give them different lightings

How many total lights do you have in your scene? I believe there is a limit to how many you can have before shadows will stop rendering for some, which could cause something like this. But it's pretty high - I wanna say 64.

@Danface I followed up with our engineering team there is a maximum of 32 lights that will cast shadows, and 48 total lights. Once you've gone beyond 32 shadow casting lights, shadows will stop casting for some lights. And once beyond 48, some lights will stop rendering.

Thank you very much @EarthQuake for the information!
