Hi Paul! Thank you so much for your response and sorry for the delay in mine. We had taken a break from Piper for a few days. As it turned out, the battery pooped out while we were playing, which ended the session we were in when I wrote to you, so I wonder if the problem was with low battery somehow, because the same circuit passed muster yesterday with the 3 crafting stations. However, it behaved strangely as a control afterward. The right button did nothing regardless of whether the switch was on or off. We weren’t bothered about this until we reached a point where we could not selectively destroy a particular thing which we needed to destroy in order to progress. (Then we went backward through the level and crafting stations to verify our circuit, and the diagrams indicated current flowing even when we had already dismantled the circuit, which you would agree is not ideal behavior for the game)
So at any rate, either the right button is not supposed to do anything once the switch is installed, or the game is buggy at that point. (As I said above, at the third crafting station we had built and verified that the circuit with the switch and two buttons was correctly set up and working)
We will surely try the whole level again, but I wanted to know if it is a known issue that the game is buggy shortly after the third crafting table. Thanks.
