I'm not sure what the question is. Are you trying to edit global strings, or use them? You shouldn't be editing strings, as that creates all kinds of problems. To use them, do something like
Lua Code:
-- this translates and prints
-- Everyone passed on: %s
-- automatically, as the game itself does the translating for you
Print(LOOT_ROLL_ALL_PASSED)
If you edit the global strings in any way, shape, or form, yes, you will crash because the game expects something, but you changed it, so boom.
