Gif not saving properly

[superjaja05]

Hello, i'm having an issue with gif saving i load a gif using local base = vips.Image.new_from_file("base.gif", {n=-1}) , then i save it again using base:write_to_file("base2.gif") (just for testing) And it seems that the base2 gif (the 2nd save) tries to "stack" the frames to save in file size, since nothing moves, but instead of actually stacking.. It just glitches out and become a transparent mess, any idea how i could fix that?
