[Game Server] Config download failure, silent deserialization, swallowed stack traces

[Flegma]

Summary

Error handling gaps in configuration loading and event processing.

Findings

• MatchService.cs — downloads configs from GitHub with no error handling for network failure.
• MatchService.cs — null matchData from JSON deserialization returns silently without logging.
• ReadySystem.cs — exception ex.Message logged but stack trace omitted.

Impact

Match fails to start silently if GitHub unreachable. Deserialization failures undiagnosed.

Suggested Fix

Add try-catch with retry and fallback to bundled configs. Log full exception objects.
