Description
When using the ClassicUO Web Client, opening a chest that contains a large number of items causes all gumps to disappear (backpack, paperdoll, spellbook, etc.). This makes it impossible to interact until gumps are reopened manually.
This issue only happens in the web client version, not in the desktop ClassicUO client.
Expected behavior:
The chest gump should open normally, and existing gumps (backpack, paperdoll, etc.) should remain visible.
Actual behavior:
All open gumps immediately disappear from the screen after the chest opens.
Environment:
Client: ClassicUO Web
Browser: [e.g. Chrome Version 139.0.7258.139 (Build oficial) (64 bits)]
OS: [Windows 11]
Shard: [Ultima Alianza]
Additional notes:
The issue does not happen in the desktop version of ClassicUO.
It seems to occur only when containers hold many items.
Happens consistently when opening chests with a lot of items.
Reproduction steps
Log into the game using the web client.
Place a large amount of items (e.g. 200+) into a chest or container.
Double-click the chest to open it.
Observe the result.Screenshots
