I'm still running into a bug with close lock. This time I noticed that it appears to be related to not being turned off for some units when they move away. Weirder still is that it seems to "spread" to other units that were never close locked. The other thing I observed is that it might have something to do with the leader being close locked. That seems to trigger it. I will keep looking for more precise details.
