i havent encountered the first part, but the second half isnt something to be concerned with i do not think.. you need to take into account that this mode is comprised of other people's contributions. SDX is developing parts for other mods than this one alone, those resources appear to be visual effects, nothing thats going to throw this game into a failure The word "Spectrums" alone suggests a lighting efffect. Having personally been through the SDX git, i can tell you that they are developing Unity themselves and these resource references are MOST LIKELY tying into one of SDX's other projects. It is entirely possible that they may come into play for version 5.2, but as there is an SDX developer actively contributing to this mod (Sphereii) I would wager that if these "errrors" were something to be concerned with, he would have made Dwallorde well aware.
