In addition to not being able to use the look at options for lights while in the Octane Render view in Solaris, I came across this bug of a light suddenly not working after just tweaking the exposure value. After this happens, neither intensity or exposure values are registered and the light remains off. Two screenshots are appended so you can see the scene.

Hmm I was kind of able to reproduce this, where after messing with the light it kind of stopped working, but was fixed after reloading the scene.
Will play with this some more and try to find a reliable way to reproduce this, otherwise it'll be hard to fix. Do you have a scene where this problem is consistent?

That's the issue, it wasn't happening on a regular basis. Sometimes the lights were working just fine and other times I would alter just a simple parameter, causing a light to not work at all. I wonder if it has something to do with having a light mixer wired into the chain elsewhere?
