I traded my EXP share held by a Pokemon in an in-game trade, forgot about it and have just realised after saving.
I've looked at the back-up saves in my 'Saved Games' folder but there are only 2 files and they're both after the trade.
If anyone is willing to trade a Pokemon holding one please let me know.
The only things of any worth I could trade are a Squirtle or I have a Tyrogue with decent IVs (HP 31, Atk 26, Def 26, Sp Atk 18, Sp Def 31, Speed 31). I'm not sure if all Tyrogues traded for the Dunsparce in-game have those IVs or not but they're the IVs mine has.
Reborn is too hard to play without the EXP share!
