Title. 

t[7] = "windows"  -- {TEXT, rooms/present.moon}

The above line exists in text_english.lua, but is missing in text_translated.lua. I haven't found any other line that is missing.

(Just adding the info here:
You can add the string with its ID manually in the" text_translated.lua" file, and translate it like the rest of the game to fix it)

Thanks for finding that one out !

Thanks for the heads-up, localization kit updated to 1.01
If you prefer to keep using what you have, you just need to add the following line inside text_translated.lua, anywhere after local t = {}

t[7] = "windows"  -- {TEXT, rooms/present.moon}
