I see the settings now as well! it might not be able to handle 5 years worth of time. Did you try a lower time to test it and see? Also did you stop your server when making the change? Then restart it after
Are you talking about for clustered servers as well? I know when I had the uploading checked to on. I was able to actually pull stuff off the obelisk that was from a SP server and it was in he ob for probably 7-8 months and it was still there.
I have not been able to just yet, I've been away from the house and have had many players on an increased tame speed day, but I did set the time to 1 year and I will work my way back from there once I can safely reset. Is a full shut down different than a restart?
