the quickest way to track any weird behavior down, it to get a lot of debug printed out. i added some SendClientMessageToAll inside the sscanf, and nested the sscanf into a if(). if an invalid line gets read, it will show you ingame what it contains.
and it seems that the file is closed too early. pay attention to the if(file)...

i cant test that out, so i did only easy stuff for debugging. its a good idea to backup all house files, and work with a "limited" version, like 3-4 houses only, all created by hand... good luck!
