Considering the previous post announces Pokemon that have reached Level 100 are not able to gain EVs, according to the PixelmonMod bug fixes for 5.1.2, we have made an alternative solution to the players that still want to EV train their Level 100s.
You'll need to collect these specific drops and turn them in to a HeadMod+ in game and in return we will give you the necessary EVs that coincide with the amount of drops you give us.
2 mushrooms = 3 sp atk
2 redstone = 3 atk
1 lily pad = 3 Special def
2 fish = 3 Def
2 sugarcane = 3 HP
1 glowstone = 3 speed
For any questions, please do not hesitate to contact a staff member!
*This is only for players on version 5.1.1.
