Hey, i think you should report that as a bug.
Those changes are replacing zeroes with “really tiny numbers”, which ideally shouldn’t be happening.
(Unless you have a script that is making that change)
Thanks for the reply.
No scripts. I don’t know by 100% who modified light but I has only particle system and light prefab.
I try to report a bug a little bit later.
