If you save a hip file with Light Linker pane opened, hscript will rise an error during loading this file, saying as mentioned in topic.
Not sure what goes next, scene is loaded but hscript stops executing others commands form script it was called by.
Saving the same scene again after closing linker pane returns peace in house.
