Thank you so much! This does all make sense how you laid it out, but I get a totally blank histogram for some reason... tried tinkering a bit but it's always blank. Not blank for you I'm guessing?
Huh. Yeah, I'm definitely getting results. Here's a histo for 2xred D6, 1 yellow d6, 1 yellow d8, and 2 green d10s vs 2 defense. Here's a link to that specific file in case something got messed up: https://www.dropbox.com/s/0882a9q6w895w8h/Red-Green-Yellow.mcd?dl=0
Ah yup that did it! Thanks so much for the help.
(I do still have this strange issue where copying anything, with ctrl+C or the button in the edit menu, crashes the program immediately. Strangely, even after re-installing, this happens on my desktop pc, not my laptop. Not a big deal, I just use it only my laptop, but let me know if you want the crash logs or anything. I'm guessing this doesn't happen to most people so not too worried about it.)
