I created my world in 1.2.1 version of Omnifactory, finally decided to use the void world feature and teleported there close to when it was becoming night time. Placed the bed, set it as spawn, and proceeded to sleep but it would not change the night time to day time or fast forward like normal. If you need any other info from me, please contact me through discord as I am a member on there.. UN is StephJ2Fan

Quite possibly can'tfix, but yes, it would be nice if this can be fixed.
