Do you mean idle goblins loitering around in the base or are there other places where sprites are missing? I think I know where the idling base sprites are in the game files, but I want to make sure.
As long as you follow the rules I posted it should never break. Unlike some games (as I am now discovering), Goblin Burrow's text handling is actually extremely robust. As long as you are just inputting a single line of regular old English text and don't use any ';' there is nothing you can do to break it I am aware of. If you know how to use Python I can send you the script I use to stitch together the CSVs with the game files, but if you are clueless on the technical stuff that probably isn't much help

Bug testing is also comparatively easy to doing the translation, so don't worry about it.
