After i lose a battle with an npc, i cant seem to battle them again with after i healed my pokemons. I don't really mind if it happens once in a while but this happens every time i lose. This kinda wastes chances of getting EXP since wild pokemons don't give out much EXP. Sometimes it's not even my fault, the server may have restarted while i was in battle.

 

I'm not sure if this is just me or others have experienced this.

To be honest i haven't played pokemon in a long time until i found PRO, and what i remember was that you can and must re-battle trainers on the road if you have lost with them. Since i've never played pokemon X and Y, i may be wrong though.

You can rebattle them after a week's cooldown.
