I recently rendered some orthos and I switched my scene world from my nebula hdr to just a grey background to get even lighting all around. Now when I switch back my sun lamp is acting strange and I have no idea what's causing it. It's like I accidentally messed with an exposure setting that only affects lights, emissive materials don't seem to be affected.
The next thing I'm going to try is just to append everything in a fresh file. I have no idea what to do.
This seems to only be happening in cycles, eevee seems fine, but I don't use eevee.
