Automated Triage

Issue type	bug
Affected area	Avatar Rendering (thumbnail loading), Backpack UI
Feature category	Secondary
Severity	SEV-3 → 2-medium

Reasoning: The Backpack UI is a Secondary feature. A thumbnail load failure degrades the Backpack grid but does not block main flows — users can still explore the world, sync avatars, and interact with other features. This maps to SEV-3 (secondary feature degraded) and the 2-medium label.

This is a duplicate of #8902, which reports the same ThumbnailLoadFailedException error from ECSThumbnailProvider during backpack/avatar operations.

Both issues stem from the same thumbnail loading failure scenario. Please follow #8902 for updates on the fix.

Related: #8891 (different failure mode of the same system - timeout scenario)

Automated Triage

Issue type	bug
Affected area	Avatar Rendering (Backpack Thumbnails)
Feature category	Secondary
Severity	SEV-3 → 2-medium

Reasoning: This is a thumbnail loading exception in the backpack UI flow. Backpack functionality is classified as a Secondary category feature. While this exception degrades the thumbnail display experience, it does not prevent users from accessing the backpack or equipping wearables — core gameplay remains functional. The issue is appropriately labeled as SEV-3 medium severity.
