Can no longer play the world I was hosting for me and my partner; we updated all of our NVIDIA drivers, disabled Steam Autocloud and restored the live account under Local/R5/Saved/SaveProfiles back to the last working time, but now anything going forward we have to revert to that exact same backup to play the game at this point thus progress locking us.
This includes restoring from both save profiles on the 30th of April, and going forward as well as trying to restore from the one yesterday.
The result is similar to everyone elses issues, where one of two things will happen; either it will load once restored from the earlier point, resetting all of our progress or it will not load, instead loading the audio from camp and freezing on the map-tip load screen before giving an application hangup error in the background, crashing to desktop.
I've also updated drivers for both of our PCs; has anyone found a workaround that does not potentially involve restarting the charecters; and understand the Devs have a public test system designed to test a new save system but looking to see if we can preserve our stuff and just stop playing until this fix is deployed.
