I can confirm that this issue is still occurring sporadically, playing on Minecraft 1.10.2. Yesterday I was able to carry lava around in buckets just fine, but for some reason when I tried to do it today I encountered this issue where I would fill the bucket with lava, and then I would walk a little ways and look down and see that the bucket is empty.
