The game is ruined because pop up won't happen at all causing you unable to feed in training items and equip in battle items... better to abuse so that it raise their training stats instead since items are all can't be used and can't be sold.

Only POW pet is near impossible to beat the first few months of cups because of it's lack of recovery.

Due to the bug these are the difficulty if you chosen the starter three.

The Red Dino : From Hard to Nightmare. (you have to pray that you have two days to train perfectly on its defense so that you have more HP via DEF... still weak against poison users as it drop HP via % of max HP... it will be easier once reached level 5 but still weak against poison.)(one of the dino enemy is retardedly OP which probably only the Unihorse abusing the attack drop bug can defeat... it has too high stats... fast...bulky and hurts alot.)

The Unihorse : From Baby to Easy. (Very Easy if you abuse the light beam bug have to hit the enemy 2 more times after the 1st hit before the debuff fade away and the enemy will only hit 10~15% damage for the whole battle)

The Bird : From Quite Easy to Normal.
