Description

I'm participating in the tavern "Pets - Collect Them All" challenge and one pet added as a to-do later in the challenge while I was already a participant doesn't appear as a to-do on my personal list.
Dewines and Alys checked and told me I was missing the snail to-do. Dewines also confirmed that at least one other member and the challenge owner are missing the snail to-do as well.
Other updates to the challenge have reached me.
I don't think this is related to my browser/computer, as I can't see the snail to-do on the android app, either.

@Luzino I have given you the Snail To-Do, but please check it and post here if there's anything wrong with it.

Also post here if you notice any problems sorting your To-Dos (you should not have any as a result of the change I made, but I'm mentioning it just in case I'm mistaken; you might also have had sorting problems from other causes).

As soon as I can make time, I'll do the same for the other participants for any tasks they are missing.

[Luzino]

@Alys Unfortunately the Snail To-Do is not showing for me. I disabled all browser add-ons to make sure it's not being blocked by something, but it's not there. I cleared my cache and tried again - nothing. Then I checked via the android app and it's not showing there, either.
The order of my to-dos seems the same as before and sorting works.

[Alys]

Ugh, sorry, I see what I did wrong. Please sync and look for it again now, and I'll just delete this rather useless Snail To-Do from my own list. :)

[Luzino]

And there it is - top of the list. Even including its correct challenge tag! Thank you. :)

Is this still an issue?

[Alys]

Probably. If we don't yet have success/failure checking and failed updates
being repeated, then this bug can still occur.

Just a note on this, to fix we should do:

1. Remove duplicate data and sync with the challenge when we can
2. Move processing to a worker via a queue system. I have a Kafka PR out now that should help with this.

[TheHollidayInn]

Have we had any recent reports on this?

[TheHollidayInn]

Feel free to reopen with user reports. Closing for now.
