Constant Combinators that are placed by construction bots will not have their active light turn on unless manually turned off then on again or the save is reloaded.




The top combinator was placed by hand, then copied and pasted via the use of blueprints to create the bottom combinator. Despite having the exact same settings the light for the bottom combinator is not on.
Saving the game then loading it will cause the bottom combinator's light to turn on, as will manually turning the combinator off and then on again.


Edit: Changed image URL.

The image in your post isn't visible (Error 403: Forbidden), you should use an imagehoster like imgur or attach the image directly to your post ('Upload Attachment').

In this case the bug is relatively straightforward and easy to reproduce, I guess your image looked something like this:

Strange... Was hosted on Google Drive as a public image, but it seems like Google's changed how that works so you cannot directly link to the image URL anymore
Fixed the image, but yeah, it was basically like that.

Fixed for 0.15.
