Experiencing similar lighting glitch in 1.14.2. Two completely enclosed farms (one witch, one creeper), above ground in the water, and it's as if the blocks aren't there when it comes to lighting. So far my experience has been it being with user created buildings, natural generation doesn't seem effected as of yet (natural spawners still dark, mineshafts and caves, etc.). Will try to clear lighting cache, see if that works for now. Figured I'd just add my voice to the crowd as opposed to opening new ticket, having it closed and moved here anyway :^).
