Farms, mines and other tile improvements were disappearing. They would show graphically on the tile, but when you hovered over that tile, it would not show that the improvement existed. I would have to rebuild the improvement. One other little thing that happened at the same time was that it was always recommending me to build a trading post on any tile with food resources. I had like 5 cities, and it didn't matter which city was working the tile it would recommend a trading post.
Edit:
So I found an auto save where it was doing this. Three turns in I had a worker recommended to build a trade post where a trade post was already built. Last night when I was noticing this, it was going on with farms and mines too. I don't know how to upload the saves though. If someone could tell me or point me to a post that explains it, I would be more than happy to.
But in these screenshots you can see what I'm talking about. One shows the worker on the tile with the recommendation to build a trading post where there already is one, and one shows the worker on an adjacent tile so that you can see the icon recommending to build a trading post there and the graphic of the trading post already there. For the record, this is not the only tile it was doing it on and some of the tiles it did it on had been improved for a very long time, so it's not like something interrupted my worker and caused him to not finish building the improvement.
