that much coding
I don't have the source code of the game, so my choices are actually very limited.
I change a few variables here and there but overall it's far from being "that much".
The most heavily modified realm has something like 30 bytes of difference with Zanzarino's trainer. That's 0.001% of the whole file

Anyway, I know that some players (including me) consider version 1.13 to be more balanced than 1.14 so I don't really feel like trying to fix this "bug".
