Cool! My next patch will have all ranges fixed.
P.S. Patch uploaded:
Not much tested, unfortunately, since my computer is overheating (UFO:AI takes 100% CPU). For the new research costs to work the player should probably get one scientist after each mission for a total of 100.
What does not work: incendiary things only do fire damage, multiple ammo for the same weapon cannot be reloaded, grenade ranges are hard-coded, some models are missing (can be substituted by similar ones, but now it's easier to see them), many particles and sounds missing or just plain wrong, lots of unnecessary ".0" in the GUI, lots of fine-tuning still to do.
Sorry for any problems and see the wiki [[Equipment]] page for some more details and to report balancing problems, wrong names, etc.
