There is a known bug (found out last night) with Autosave OFF and Save and Exit sometimes hanging. The good news is that it has already been fixed in the next upcoming fix wave.
Possible, this theory. Won't get too deep into those weeds, but Legacy and Multiplayer are the most often places where issues seem to congregate. MP will be easier to clean up. I have some ancient worlds (read: created the day of initial console launch on old gen) on my 360 that is sitting in the floor next to me. If I can scrape up the motivation to find all of the cables, etc. I may try to up/down my files. Thought I had cloud'd them before, but nope.
Interesting. I've spent a ton of time in UG Ice on my play thus far with no issues. Legacy or New? Gear?
EDIT: I see where it may just be endgame gear that triggers the issue. Will check back periodically in my worlds.
As the usual designated builder, I can understand that - I would be at full
stage.
Appreciate your help - any that you or anyone else can give. Terraria is a daunting beast to QA, if you think about it. Practically infinite variables. Will share that there are some world conversion bugs (for example) that are literally tied to one specific players' worlds that - as far as anyone can tell - do not occur in any other worlds.
PS4 or XB1? Cloud save?
I have had this reported to me by another user in regards to other Filter Effects (the atmospheric effects you get with the towers or blood moon, etc) right as they start. I think this may be all related to that - a flash of white at changeover. Will be on the lookout for this myself as well.
