When attempting to upload a bundle to Roblox, the upload process consistently fails at Step 4/4 “Generating bundle ID…” The progress bar reaches 50% and remains stuck for approximately 2-3 minutes before displaying “Submission failed - Unknown error” message.
I’ve tested this issue extensively - it persists across 3 different verified accounts and 4 different versions of the bundle I’m trying to upload, including bundles that previously uploaded successfully. All bundles pass validation without any errors before the upload attempt fails. Based on DevForum reports, this appears to be affecting multiple creators and is specifically limited to body bundles, as other asset types like accessories and heads upload successfully without any issues.
I have attached the bundle as well as the blend file in the private message.
Expected behavior
The bundle upload process should complete successfully after validation passes. Once the “Generating bundle ID” step begins, it should progress from 0% to 100% and then either show a success message or proceed to moderation queue.
