From past experience with this and other games, it might be useful for the posters here to indicate what malware/anti-virus software they’re using.
Some of them buffer up changes to files and then don’t commit them if they’re unsure that the files in question are okay to change. I know MalwareBytes had an issue with this for a bit as well as a few others.
This has all the earmarks of the same issue - software detects and out of date condition and downloads and “writes” a patch and then doesn’t see the patch applied so it does it again.
It might be interesting to see if there is a commonality on what system protection software is in use because I’m not seeing this problem at all but some of my guildies are.
