Mobs not affected by sunlight

This issue affects chunks that were affected by MC-142134. The lighting now appears to be correct in these chunks however mobs spawned during the night are not affected by sunlight during the day when they are in these chunks.

The debug screen shows light levels of 15 within the affected chunks. If mobs walk outside of the affected chunks they start to burn. They stop burning when they move back into the affected chunks.

I haven't seen mobs spawn during the day in these chunks.
