NPC End Turns Taking Forever

Just started happening. When NPCs end their turns, it is taking around 15 seconds to register and continue. I verified files, restarted the game, and my computer – no luck. Anyone else having this issue?

I assume this is related to the recent update. It’s unplayable for me in this state and I just plain don’t like real-time mode. If anyone has encountered this and found a solution, please let me know.
