I’m 85% through PR4. ALL of the main quest elements are done — now it’s just side quests.
I was debugging Zachary’s side quest a little while ago — some odd bugs, but nothing I couldn’t handle. Latest build testing, everything’s going great, we get to the big finale, and… this happens. (Slight spoilers)
This is what happens when you accidenally stick a CreateObject command in an infinite loop. I nearly fell off my chair laughing when it happened, but I guess you gotta be the developer running on very little sleep to find it that hillarious. :)
