Crop planting in low light area - light source updating is buggy. Expect crops to pop out immediately after updating light. Not the case. Taking light away does not cause crop to pop. replacing light source then causes it to pop. sometimes pattern of light source is incorrect (not regular diamond of light level)
One bug per report please. Partly duplicates MC-132491. Could you attach screenshots or video of the light pattern issue with the debug screen enabled (F3)?
