Third route isn't more buggy, it's the numbers that are so fcking massive that it makes Mtool crash, for me the crashes where only when 1. starting a battle 2. during a battle 3. when a battle ended. So when I disabled encounters, obviously can't with bosses
I had no crashes for like 7h, but when I re enabled encounters to try and recruit new enemies I crashed like 8 times in 1h, so it's most certainly loading the massive numbers that causes problems with Mtool, I mean we are talking billions of health and damage in later stages, so :s
