Sprite import error

[YarTom]

Describe the bug

Graphics import error.

As far as I understand, the errors occur because sprite count in the "Out" folder starts from "_1" instead of "_0". In any case, this is a bug.

When I try to load this sprites into the game (choosing the folder containing all four folders), the import succeeds, but after saving and reopening data.win, this error occurs.

Also, if I try to open "sLambdaruneBlackLogoOut_ru" sprite (before reopening file), this error occurs:

The most interesting thing is that importing folders separately (first "Out", then "Mid", and so on) does not cause same problem.

Also, a strange thing I noticed: if you create a new file in UTMT, then import sprite (even if you number everything correct (from zero)), and then try to save the file, the message "Flushing remaining buffer data" will hang indefinitely.

Reproducing steps

1. Download this sprites
2. Open any (Not empty) data.win
3. Import sprites (Scripts - resource importers - import graphics), choose the folder with "Glitch, Logo, Mid, Out" subfolders.
4. Reopen file or try to open sprite "sLambdaruneBlackLogoOut_ru"

For 2nd:

1. Download this sprites
2. Create empty file
3. Import sprites (Scripts - resource importers - import graphics), choose the folder with "Glitch, Logo, Mid, Out" subfolders.
4. Try to save file

Setup Details

1. v0.8.4.1
2. Linux mint 22.2
3. It works with any data.win I tried (for example main menu from deltarune)
