Lost all Chaos progress in Laboratory 0 after impromptu maintenance

I was playing in Chaos in Laboratory 0 and then saw the maintenance warning (Saturday, Nov. 15) but I only had 30 minutes to finish the inner layer, so I thought I could just "save" my progress by doing the temporary return after reaching a checkpoint.
After the impromptu maintenance, all my progress is gone. It would have been a pretty damn good save file too. This wasted me so much time...

You either need to provide WAY MORE advanced notice of these maintenances, like at least a day in advance OR ideally fix the game's engine to support saving Chaos progress across maintenances. There's no way everyone can always sit down and do full Chaos runs from start to finish because they are scared this random progress reset will happen. The official Twitter tweeted the maintenance notification like 4.5 hours in advance, but I checked Twitter a few hours earlier than that and didn't see any announcements... There's no way I can constantly check Twitter every few hours to make sure this won't happen.

😩 no proper compensation 'en... this game gets kinda stagnant once protos is level 50 lol I'm even going back to do my daily MDs on limbus rather than pointlessly farming for 4 copies (poor luck couldn't care less lol would go as far as to say that my saves on uma musume are much better since they don't get corrupted unlike this game 🫡)

S1761419432300011, that's the standard reward everyone gets for each week of November. We've been getting those since the 1st week of November. It was for the general stability issues that people encountered at launch.
