Hi Ash1989ley and everyone else adding their details to this topic,
I posted an update in the “Known Issues” thread for this: [Known Issue][PS4/XB1] Stuck in "Cleaning Up" phase on load
The team are working on releasing a fix for the issue though this is mostly related to items dumped by players. I’m still working to get as much information as possible to them about any other potential triggers that may be causing the same issue. As soon as I have more details on patches, I’ll update the known issues thread.
For now the issue appears to affect single player most mostly. It may be possible to avoid the issue by player multiplayer on private. While I understand this is not ideal, I hope it may help some players while the team continues to work on fixes.
Thank you all for sharing the details of your experience so far.
