Hm, so it only affects his machine and not yours?
There definitely must be something about his setup that’s causing this.
Basically from the log it looks like he has something unsuccessfully trying to link to Deactivate, DeactivationBroadcast_Implementation, and ReactivationBroadcast_Implementation.
All 3 are functions which didn’t exist in previous version, so that’s why i’m thinking it’s version conflict of some kind.
(can you send me the project files? i’ll try to find what’s wrong)
