Hi, no, everything's fine. I was just not sure before buying as the description clearly says 16x16 and doesn't mention the other sizes. I went for it anyway though and yes, they do have x2 and x3 sizes.
One thing though... either I am blind or there are no autotiles in x2 and x3 sizes (only in the basic one)... I mean the tiles in the picture below, they are only in the base tileset in the terrain.pgn file it seems.
The 200% and 300% versions have autotiles for the RPGMaker format. The autotiles on that terrain sheet are in the Game Maker Studio 2 format. If you want to use those ones, then the easiest way would be to upscale that image instead of re-working the RPGMaker ones. My friend fmoo made some simple upscaling tools that can do that really quickly: https://fmoo.itch.io/autotile-packing-tools
