it might be a mistake in moves code… so this is an example of how it should look: 570,“Zorua”,93,0,Female,Adamant,31,31,31,31,31,31,311,453,26,25,-1,-1,
Every Detail of the code matters or it will glitch the egg making the game crash when it hatches.
i think i’ve figured out why it crashes when a new move is learned, every egg you generate MUST have 4 moves, in this case 311,453,26,25,-1,-1, you can repeat the moves, as in 311,311,311,311,-1,-1, but there must be 4 and two ,-1,-1, at the end, ALWAYS or it will glitch and crash whenever a new move is learned 
this applys to every egg, not just Zorua
Hope this helped
