I have found a little bug in my game, I have tryed to use a combinator over lights but if lights builded by robots doesn't work. if builded by hands it will be ok.
i have try it many times.

i use 14.21 version

We use robots to build light logic all the time and it works fine. Please post a save file with a simple blueprint that will not work when build by robots, have the working hand build setup next to the character.
