Invalid chunk ASE_FILE_CHUNK_FLI_COLOR2

[redbug26]

Chunk ASE_FILE_CHUNK_FLI_COLOR2 is invalid when palette > 256

aseprite/src/app/file/ase_format.cpp

Line 679 in d70801e

fputc(pal->size() == 256 ? 0: pal->size(), f); // number of colors

Thanks for reporting this bug @redbug26, I think the best thing to do in this case is not to write the color2 chunk at all (as it's only there for backward compatibility with older versions of Aseprite and we generally use the palette chunk that does't have this issue).
