Client-Side Anomalies and Server Enforcement: A Case Study of witch.mdl Consistency Errors in Left 4 Dead 2

| Cause Category | Specific Trigger | |----------------|------------------| | | Custom Witch skins (e.g., "Summer Witch," "HD Witch") that replace the vanilla .mdl . | | Corruption | Partial update, hard drive error, or interrupted file validation. | | Version Mismatch | Server running a beta branch (e.g., population_flood beta) while client runs stable. | | Add-on Conflicts | Two add-ons both modifying witch.mdl without proper load order resolution. | | Server-Side Custom | A server owner replaced their witch.mdl with a custom version (e.g., invisible Witch), forcing clients to match it. |
