I'm at the conuncrum door in James' memory, to the right of the Golem Biom Anchor, where I have to use the conundrum device to send waves into the door to open it. It's the on where the door is covered with carved arabic numerals (1, 2, 3, etc) with three sets of Cistercian numerals. So obviously I'm supposed to just put in the Cistercian numerals into my conundrum device.

Pretty obvious, except it doesn't work. The first two worked fine. 2448, and 5841. The third one is clearly the Cistercian symbols for 6911, but when I put that in and hit "Send Wave" nothing happens.

I think the puzzle is broken. I had to turn on the assist features to skip the puzzle because it wouldn't work.

It's honestly a shame. This game is so stylish and has such a good story, it's obvious they spent a lot of time on it. But then stuff like this, like the janky combat, the poor optimization, makes it feel like they just didn't care at all.
