I found two tiny little errors in the game script.
en-GB's STR_ARMOR_ strings for UFO and TFTD say "ARMOR" when it should be
STR_ARMOR_: "ARMOUR> {0}"
(if this isn't true in OXC, it's an OXCE problem, but it probably is, honestly)
and in OXCE, the soldier appearance selection menu in UFO uses the feminine "blonde" for the male appearance, when it should really be:
STR_AVATAR_NAME_1: "#01 Male, Blond"
Wait, should this be in Suggestions? I've seen bug reports here, and this is kind of like a bug report...
