P.S. On what difficulty level did you play it? The thing is that, for example, the latest version of the map "Grand Rubicon" can be played on "Veteran," but it crashes after the first turn on "Hero."

I can't say anything about the latest version of "Grand Rubicon" because I haven't played it (it's not appropriate to discuss it outside of its dedicated thread).
"Unicorn Empire" was played on "Hero" for my own enjoyment; I'm currently playing version 1.1. On "Warrior" and "Recruit," I only reviewed some of the maps (2, 4, and 5) from the original material. All difficulty levels are equally functional, at least for me. I used two different computers – a laptop and a desktop – to play the game, transferring the files from one to the other. I agree that it's not possible to have the same glitches on different computers.
