So i have heard that a few players are losing their savedata randomly and according to what they tell me, it looks like the saves are rolling back to a previous save from 2 servers ago.
Someone described everything he did to me:
So I had an Old Boat in Slot 1… I deleted that boat and saved NOTHING to slot 1 (Basically I cleared Slot 1) I deleted the Boat and the name of the Boat which was Ironclad. I built a Submarine and Saved it to Slot 1 (I built the Submarine on a NON PVP Server), I switched servers sometimes and all was fine, I kept working on the submarine and when I was almost done I switched to a PVP server via the Gamemode button in the right corner. I joined on a PVP server where I found my friend, I spawned my Submarine and left (While the submarine was still spawned) and played Bad Business on Roblox for 5 minutes, I then joined the SAME PVP server as before because I joined Plane Crazy through following my friend in-game. My Submarine I saved was now my Old Boat again, it even had the old name Ironclad, my Auto Save slot was an Destroyer, I had recently played with. So Slot 1 was put back to the Old Boat and the AutoSave was a random destroyer I recently played with and my Submarine was gone, (What should be noted was that I painted my destroyer before building my Submarine and the paint was now gone too, on the Autosave as well as on Save Slot 5 where I saved my Destroyer Painted…) anyways I rejoined (again through following my friend in the game) and it was still the Old Boat and not my submarine, I clicked Undo but it just deleted my Old boat so I clicked Undo again and my Old Boat was there. I then joined Plane crazy via normal (Planecrazy Roblox click the play button) but the problem still was there, my Old boat was on Slot 1 and my Submarine was gone.
The same thing happened to the rest of the players, they were a few servers ahead already and lost 3 hours of playtime because the savedata got rolledback from a server they were in a few servers ago.
I see no errors and no issues in my scripts, everything should work normally, its just really rare situations like these where people lose their data.
