It just happened again and I can supply full documentation:
Note the repeated edits by both Nocturna and Discovery. They are actually two separate comments, but because they share the same comment ID any edit to either comment actually ends up changing both comments.

An Ear Worm is like a Rickroll: It is never going to give you up.Another incident. I'll try to report absolutely everything, but this is the last one I'm going to bump. (If my hypothesis about the cause is correct, instances will theoretically increase as time goes on.)
^ I think it's supposed to mean that they are the one responsible for their own amnesia.

Sorry I missed who actually posted the previous comment (certainly wasn't me). :(

An Ear Worm is like a Rickroll: It is never going to give you up.Randomly generated unique ID collisions have happened before in other contexts. There needs to be some way for the system to recognize when it's done this.
"It's Occam's Shuriken! If the answer is elusive, never rule out ninjas!"The current YKTTW is actually better at handling collisions than the old YKTTW, it just continues to occur when comments are queried without their accompanying YKTTW ID — specifically, these two cases only:
- Immediately after posting a new comment (displays wrong comment until page reload)
- When editing a comment (displays wrong markup, affects both comments when submitted)
(The old YKTTW had a third case when loading the main YKTTW page, but that's long fixed)
An Ear Worm is like a Rickroll: It is never going to give you up.

Can't find my old thread on it atm, but the old YKTTW-replies-mixed-up bug is still occuring.
Basically it's just the new-reply code (where it displays the comment you just posted) and edit-comment code that still need fixing, they need to use both the comment ID and YKTTW ID as arguments.
