Friend can't move after encountering Damian at the Utira Library/Unable to trade

[Naeem Milord]

For whatever reason he can't send a screenshot, but my friend cannot move after trying to talk to Damian at the Utira Library, he can't open his dexnav, or options either (or anything for that matter), and no error message would pop up. I had traded him a Boldore so it would become a Gigalith, and he could trade it back, but we were unable to trade. The pokeball indicating the pokemon to be traded wouldn't appear. I assure you he was case sensitive, and was typing my username exactly as it was displayed. The trade issue happened before the Damian bug.
