there seems to be a problem with some of the es/ es-419 utf strings
i deleted the es* languages zipped it and uploaded it and now the rulfile could be checked
the game seems to be a bit more forgiving than the tool or yaml online parser
Edit:
currently some errors can be a bit missleading:
like:
file/dir not found
['warning:', 'a extrasprite/sound entry is wrong', 'extraSprites', 'FLOOROB.PCK', 'Resources/Firearms_Compilation/Submachinegun/floorob_clip.gif']
there is a file Resources/Firearms_Compilation/Submachinegun/floorob_Clip.gif (c!=C in unix where the test is running) i will fix that confusing error recognition some day
