Presently, I dont have an ETA to share on that update.
Fair enough. Do you have (or are you able to request) any more information on what actually triggers the save corruption so that while we wait we actually know what to avoid in the game so that it doesn't happen? I'm sure a lot of people would feel much more comfortable playing the game if they weren't afraid of losing their game with each passing save.
Sure, there are posts giving ideas about major areas to avoid, but some people manage those areas without issue, so a real list would be good.
If we could at least avoid the save game corruption we can roll back to other saves to try and get around quest bugs.
