Pen tool problem

I’m making 32x textures right now, and somehow when i draw with the pencil tool on this specific image, it draws lines like is showcased on the image. It won’t let me draw any other shapes. I don’t know how I did this and I’ve been using Aseprite for around 6 months now.

Most likely snap to grid is enabled. There should be a big disable snap to grid button in the bottom right.

Thanks for the quick response!
