Australia Daylight savings messing up with the daily streak/reviews on x date.

[SimplyEkra]

Problem description

On daylight savings for Australia (2am AEDT on Sunday 3 October), my Anki has an blank box for reviews, but my Anki still says my current streak is 195. I thought that I just missed my Anki reps, but since my streak was still going I thought that was weird, and I didn't give it too much thought until another Australian in a Discord server also had the same problem as me. Note: I updated to the latest Anki version, but I'll revert back to Anki 2.1.35 to get my addons to all work. Since Migaku hasn't been updated. Might not be relevant though.

Checklist

Please replace the space inside the brackets with an x if the following items apply:

• [x] I've restarted Anki to see if it helps
• [x] I've verified that I use the latest version of the add-on by redownloading it from AnkiWeb
• [x] I've verified that I use the latest version of Anki by checking at https://apps.ankiweb.net#download
• [x] I've tried to disable other add-ons to see if there are any interactions present
• [ ] My issue disappears when I hold shift while starting Anki.
• [x] I've checked if anyone else reported this problem before by looking through the issue reports. I also checked to see if there is a section about known issues in the add-on description, documentation, or README.

I have the same issue. Purely cosmetic but left me scratching my head. I'd forgotten about DST as the likely culprit.

Yeah, I ruled it out as well, I just thought I missed my day, but the streaks were not resetting. It's only until someone else pointed it out that I realised, and then it kept getting mentioned agian by more people, and since it was on the exact day, I think it's the most likely culprit.
