Fix the Inventory Duplication Exploit

4s 256 MB
✦ ExclusiveAdvancedNetworkingSecurityDataStoresProduction

Players found a race condition in the trade pipeline that clones any item. Reproduce it in the sandbox, read the server logs, and patch it without breaking legitimate trades.

Implement guard(txn), an idempotent commit check.

“Every dupe starts as a race condition nobody thought could happen.”

From one script to a studio.

A Roblox game starts as one script. Shipwright teaches you to grow it into a production system, and keep it alive when things break.
