Acquired 4 strings. Brought to workshop. System accepted strings but did not register transaction. now stuck 3/4 complete.
pixel_player32846730 I would double check if I really had collected all 4 strings (placing the 4 boulders; image 10-5) and also collect all the other required things. If still stuck you will have to contact support. As far as I know there are no known problems with this mine.

Roeland Thank you I have collected all four strings. the ropes are not available to open the pull cord in the basement. I gave the ropes to Kane in the workshop. I will try support.
