It took me a bit to not start singing a shanty there...
[Ahem] So I came across an old question of mine, it is a very old question; to the point where it could be deleted and no one would notice. Do cauldrons catch rainwater? minecraft-java-edition, posted in 2016.
The question is fine, however the answer has a video link that has since been deleted. Again, the answer is also fine, capturing the information from the video in a quote; so again the answer is still valid.
However, now there's a big black "Video Unavailable" block covering half of the post. What should be done about this kind of thing?
