The bucket is full of water, which can be poured clean on land, but pouring water into the sea is not allowed. as long as water is poured into the sea, there will always be water in the bucket, which is always not clean. only the 20w18a version has such a situation. none of the previous versions have appeared, and it is still expected to be repaired as soon as possible.

（I recorded a video in which I turned on subtitles to see that the water was empty, but there was still water in the bucket.）
