I was trying to grab some tiles from a gif file that consisted of 32 colors, and I had intended for them to maintain those colors. First I attempted to convert the target tiles to 8-bit before ripping to prep for it, but when I performed the grab the tiles lost their color and reverted to standard 4-bit cset style (1 row instead of all 256 colors).

When I tried converting them to 8-bit after ripping, the colors were already lost (Obviously).

Is there an operation or button I am missing? I wanted to ask for help first before reporting it as a bug (I didn't see it in any of the bug forums, so...). Also, the Wiki has no information on the subject.
