@jmf: In pixel art? That'd be nice
@Dioxine: I think I found why I thought there were "empty" research projects in Piratez. When you research something for which you already have the base project (ex.:
, it shows as "we have now discovered: (empty space)" (or something like that). If it still unlocks a new UFOPaedia article through GetOneFree or something, then you get that, but otherwise you get nothing, and if it didn't unlock any new project either, you end up with nothing but a "We have now discovered: (nothing)" and nothing else.
TL;DR: Since Piratez works by researching some things multiple times and OpenXCom doesn't display the name of things you have already researched if you research them again, you might end up with interrogations or item researched that don't get named, don't show any bootypedia article and don't show any "we can now research" or "we can now produce" window, leading to very confusing reports. Nothing to do for you I don't think.. but it might be worth a feature request? "Always display the name of a completed research project"?
