Title: Error: UpdateWorld <-MainLoop
Post by: Maximus on May 17, 2026, 11:32:15 PM
If you have this error:

General protection fault!

History: UMasterLevel::GetModel <- Draw <- UGameEngine::Draw <- UWindowsViewport::Repaint <- UWindowsClient::Tick <- ClientTick <- UGameEngine::Tick <- UpdateWorld <-MainLoop

Solution:

This error is 100% client-side, not server-related.

The stack trace is from Unreal Engine 2:

UMasterLevel::GetModel - client tries to load a 3D model
Draw - during rendering

Most likely causes:

1. Missing custom system files, don't have the corresponding .dat/.utx files in system folder.

2. Invalid NPC display ID or item model ID that doesn't exist in the client itemname-e.dat / npcname-e.dat.

3. The system directory is missing or has corrupted files.
