Ok, I signed up because the mods are awesome and well I noticed a bug that causes crashing in this one. The 3rd quest has half energy going on, the mod has the first two quests as 0 energy (which rocks) and the 3rd as 6 energy per battle, but because there's a half energy thing going on if you try and to do a quest it crashes.
So because of that all half energy quests are going to cause crashes if you try to play them with the mod.
*edit* Actually looking at it, I don't think there is a half energy thing going on, seems the mod is doubling the energy required for the stages, making it crash. Hopefully there's a solution to this, because the 0 energy is a godsend with vortex quests.
