Rocks'n'Diamonds

see https://youtu.be/y7VXfb-q6zc , or play back this tape: at 0:56 of the tape (or 1:01 of the youtube video) a fuse that the laser passes by gets activated when the laser passes by a prism and melts an ice tile. the laser remains on, but unable to melt any ice tiles until the fuse is deactivated

it seems this bug has some specific circumstances; i was not able to trigger it in either of these variations i made with the editor (the starting placement of ice tiles around the prism was unmodified)

Thanks for the detailed bug report, and the tape!

In fact, this is another bug that I already fixed -- the reason here is simply that there were (quite a number) of occasions where the laser beam should have been deactivated (due to the fuse), but wasn't. It lead to the strange situation of the laser apparently being active, but in fact isn't (and therefore cannot melt ice etc.).

I think I should quickly release all those latest bugfixes with a new version 3.1.1 (and a corresponding new R'n'D version).
