Hi !
Very nice extension here, thanks !
However, is there a limit for the number of tiles per spritesheet ? I'm currently trying to implement the Minecraft wiki's spritesheets using your extension(https://minecraft.gamepedia.com/File:InvSprite.png) but it seems to take forever to update the fields Column/Row/Inset : The loading circle is showing after click on save but nothing happens even after >10minutes. Is there a limit ? Or should I wait more ?
Regards,
