Trying to get Radical Heights running locally/privately — stuck on UE4 frontend crashes, open-sourced the mock server

Got auth, matchmaking, and character creation endpoints all mocked locally with a Node.js server. Game boots, but React crashes before SetSelectedCharacter fires — invisible character, no items, "Creating Match" hangs on loading screen can't load into map.

The JS errors:

• Cannot read property 'level' of undefined
• e.map is not a function
• Server returned an invalid response ({"success":true,"_fallback":true})

I've open-sourced the whole thing — HTTPS mock server, socket.io matchmaking, frontend injection, CharacterBypass DLL. If you know UE4/React debugging or want to reverse-engineer the chunk.js API parsing, check the repo:

Run it, check server-requests.log for MISS endpoints, and PR whatever you fix.
