Hello

A truly devastating bug!

At first, I thought I have accidently deleted a handful of occlusions by clicking the wrong key when modifying an IO card.

But then, I re-traced my steps, and noticed that it is indeed a bug.

I was only able to reproduce it with this card. I tried reproducing it with the other IO cards, but I couldn’t…

```auto
Version <U+2068>24.06.2 (33a92379)<U+2069>
Python 3.9.18 Qt 6.6.2 PyQt 6.6.1
Windows 10

```

Some facts about the card:

- Created on 2024-05-24
- Here is the content of the field (I have lost some clozes):

```auto
{{c2::image-occlusion:rect:left=.0476:top=.298:width=.0744:height=.0414:oi=1}}<br>{{c1::image-occlusion:rect:left=.0714:top=.0207:width=.0506:height=.029:oi=1}}<br>{{c13::image-occlusion:rect:left=.7292:top=.7492:width=.1786:height=.029:oi=1}}<br>{{c4::image-occlusion:rect:left=.5417:top=.4387:width=.0685:height=.0248:oi=1}}<br>{{c9::image-occlusion:rect:left=.7143:top=.5836:width=.131:height=.0207:oi=1}}<br>{{c3::image-occlusion:rect:left=.2589:top=.1697:width=.052:height=.0312:oi=1}}<br>{{c5::image-occlusion:rect:left=.5685:top=.4677:width=.0655:height=.0207:oi=1}}<br>{{c12::image-occlusion:rect:left=.7589:top=.6705:width=.0982:height=.0248:oi=1}}<br>{{c6::image-occlusion:rect:left=.5855:top=.4936:width=.0744:height=.0248:oi=1}}<br><img src="paste-Image.jpg">

```

- Here is the content of the slfld

```auto
{{c2::image-occlusion:rect:left=.0476:top=.298:width=.0744:height=.0414:oi=1}}{{c1::image-occlusion:rect:left=.0714:top=.0207:width=.0506:height=.029:oi=1}}{{c13::image-occlusion:rect:left=.7292:top=.7492:width=.1786:height=.029:oi=1}}{{c4::image-occlusion:rect:left=.5417:top=.4387:width=.0685:height=.0248:oi=1}}{{c9::image-occlusion:rect:left=.7143:top=.5836:width=.131:height=.0207:oi=1}}{{c3::image-occlusion:rect:left=.2589:top=.1697:width=.052:height=.0312:oi=1}}{{c5::image-occlusion:rect:left=.5685:top=.4677:width=.0655:height=.0207:oi=1}}{{c12::image-occlusion:rect:left=.7589:top=.6705:width=.0982:height=.0248:oi=1}}{{c6::image-occlusion:rect:left=.5855:top=.4936:width=.0744:height=.0248:oi=1}}

```

Have a look at the GIF below (notice how, just after moving the boxes, the clozes disappear completely):

After some tinkering around, I can see that these

These specific positions are troublesome. Try pasting them into their respective columns in the `collection.anki2` database.

You will get the same results.

Make sure you have an image (inside your media folder) with the name `paste-Image.jpg`.

I have even tried the following (cloze numbers ordered):

Thanks for the report; I’ve logged this on [Bug: Anki Deletes most/all of my IO clozes when modifying occlusion positions · Issue #3267 · ankitects/anki · GitHub](https://github.com/ankitects/anki/issues/3267). To make it easier to look into, it would be great if you could:

- Restore a backup into a new profile, from before the clozes were lost
- Export the problem note into an .apkg
- Confirm that the same steps still trigger the issue
- Rename to .zip and upload to the linked issue above
