If you accidentally hold down X for a bit while picking from the shop the game crashes.
I tried to reproduce this but no 'crash': it simply picks from the market, immediately picks the piece moving on the map area and that's it (at least for me).What kind of crash exactly? It froze or ended the program on command line?
Damn ! it seems you can never catch them all :(Unfortunately I can't seem to recreate that , could you please send over a bit more detail :') Thank you <3
