please help i lost the exp share

so i encountered the bug that if you cancel in the PC while holding a Pokemon the Pokemon gets deleted and that happened when i had an exp share on the Pokemon and i did't notice it until after i saved so what do i do? please help.

I'm sorry, I don't really think there is a way to get it back... we'll try to add in a measure to prevent that deletion bug for future releases, but we can't do anything to get your EXP share back, sorry :/
