i think so, yes. Anyway, since i remapped the "recipe" key to an unused one, i dont crash anymore while in inventory and pressing "R" (which i have an habit to do, in order ro sort inventory). The game will still crash, if you try to left click some items (i guess IC2 stuff, generators, compressors etc.) on the right panel, but i know now not to do that, so i dont get any crashes anymore.
