I do not believe this is due to the latest patch. I have had similar events happen in 2.12 and earlier. I had sent similar saves in to Illwinter, and was told that that was odd behavior indeed, but that they were unable to pinpoint its source. Perhaps if you send the appropriate files, they will be able to learn more? It often involves teleportation, but not always. I have had a GoH'ed Vastness just ... disappear, and similar stuff.
