my pleasure :-) i do a better run than before. just little bit smoother :-) and yes, we both have a different approach to the setting boulders and diamonds.

yeah thanks!   
i made a screenshot to compare both configurations. they differ at two places; the most complicated parts are the same.   
always funny to see there are multiple solutions (mostly) to these type of caves! :-)
