I think something might be wrong here.
I made another post (see here: My first YT Tutorial: Custom Nodes using GDScript! - #15 by nutlike4693). In the comments, somebody was complaining my tutorial was too fast paced, so I sent the fish video to show my inspiration.
But somebody left a comment saying that both YT links pointed to the same video (somehow?). So I edited my post to change the YT link (which was pointing to my video) to point to the fish video.
And as a side effect, it somehow changed this posts link as well.
Is there some caching/link redirection stuff going on that means multiple posts with the same links are all “connected” somehow?
