Hi Andrey,

I was analyzing the pieces of the 16-cell today. I had a lot of fun twisting it. But given the large number of pieces, I don’t think I can solve it without the macro.

I’ve found a glitch. Sometimes when I click a face of a certain cell, the puzzle is rotating around another different cell. It happens from time to time. But I cannot find a viewpoint to reliably repeat this glitch. Fortunately one time I got two screenshots:

Before clicking the red dot, we have the solved 16-cell:

After clicking the red dot on the dark yellow cell, that cell doesn’t rotate:

The cell that is actually rotated is an invisible one. Whenever this glitch occurs, it always rotates around an invisible cell. I hope this clue helps you to fix it.

Thanks again for making such a great puzzle!

Hiding of mirrored blocks during animation is in my todo list, and rotation of cell outline has very low priority (probably zero). There are some things that I have to do: timer, twist counter, optimization and recalculation, testing of log save/load commands, library file for puzzles (instead of many separate txt files), computation of main symmetry groups for 4D, and so on…
