How does it look in vanilla with Smooth Lighting OFF?

Vanilla has the same problem with farmland on Hypixel when Smooth Lighting is OFF:

Looks like Hypixel is sending to the client chunks with invalid lighting data. When the chunk is changed (placing/breaking a block) the lighting is recomputed on the client side and the bug disappears. After a reconnect Hypixel sends again the chunk with invalid lighting. Tested with vanilla 1.21.1 and Smooth Lighting OFF to see the raw light values. Older MC versions (1.19.4) behave identically.
