I searched the #platform-feedback forum for anything similar and all I found was issues with the datastore, which isn’t really the same as what I am experiencing. So this might be a rare bug or something completely different, LOL.
This bug report is related to working in Studio when something on the other end of Roblox goes offline (reboot, no Internet, whatever happens out there, etc). The first time this happened, I thought it was my fault. Maybe I hit a delete button by accident somewhere and wiped out an entire folder of models and scripts? But now that it has happened twice and I was able to spot when it happened and make notes, I hope this will help the Roblox engineers narrow down the cause. I did search the bug reports for something similar because I can “respond” to other bug reports in a reply, but no one has put up a detailed enough bug report about this specific error to work with. Ok, enough history, time for evidence.
It just happened again today (yesterday now), only an hour before this posting as I was getting together screenshots and data, doing test to see if I actually lost data, etc. To be more specific, it happened before 8:45 PM Central Time Zone, 8/26/2022
Details: An Internet interruption of the connection between Roblox and the Studio software can cause Studio to lose random chunks of your game, be it models, folders, code or anything else under the Workspace. No errors will be generated on screen nor will anything show up visually to signal the user that something has happened. You won’t know something is wrong until either you try to test your game and get errors due to missing resources or you close Studio thinking everything is saved and come back later to find random stuff deleted/missing from your game.
Where: Roblox Studio
When: Rare, hard to reproduce
Screenshots: Linked below
Reproduction: Work in Studio and either simulate a link failure or wait for it to happen on Roblox end (rare), random as to what you may lose.
Environment: Windows 7 Pro, 16GB of RAM, no Beta Features enabled in Studio, No Plugins Installed, as raw of a Studio setup as you can get. Studio never crashes or generates errors when this happens.
–No micro-dumps generated, no crashes of Studio
The links below have pictures that detail the signs of something is wrong in Studio along with further testing that shows Studio did indeed lose data because saving your game results in saving it as though you deleted a bunch of random resources in your game.
Bug Image 4, If you restart Roblox Studio (remember, it had no errors or warnings before), then you get an error about a disconnected Team Create session, which is probably the source of the data loss? Add to this, I don’t do Team Create sessions with anyone, so it’s odd that it would say that, but it’s the sign that something is wrong though and to look for data loss.
