Sorry for any inconvenience! I can confirm that the door sprites should be in the pack.
They aren’t on the core spritesheets for space and redundancy reasons, at least originally. Because I am revamping a lot of props, especially things like doors, to include animation, I have organized the file architecture of packs a little differently than before.
For yourself and anyone reading this, the place to find the doors (and other animated props/tiles) is “animated prop spritesheet” which is a folder in the pack structure.
If you still can’t find it, I would love screenshots to get a look at the folder contents for the pack you’ve downloaded. Maybe there is an issue I don’t know about.
All that said, I should also ask you if you would personally prefer non-animated instances of doors or similar included in the tilesets. This is of course possible, especially with the revamps where I am doing a lot of “alt” versions of tilesets to include variants of props and tiles. If there’s a need, even for convenience, to have these on the core tileset sheets, I can include them in future updates and in new packs with similar elements.
