I often play/leave the game open for 6+ hours. I think, after a while, either this mod or some combination of this mod and Choose Your Medicine(?) potentially prevent the game from being able to save. This has happened to me a few times, and here is the error in player.log:

Exception while saving RimTalk.Data.RimTalkWorldComponent: System.InvalidOperationException: The Writer is closed or in error state.

Let me know if I should do/write down anything the next time this happens. I mentioned Choose Your Medicine because visual exceptions seems to think that it both of them contribute to the error.
