@studworkshq: Your Roblox shop can take the Robux and lose the item. Here are 4 mistakes that cause it, with the fix for each. 1. Granting before the save finishes 2. Paying out one receipt twice 3. Trusting the client about passes 4. Testing purchases with real Robux Using the newer BindReceiptHandler? Same rule: return Processed only after the save, and NotProcessedYet if it fails. Works for developer products, passes and in-game coin shops. Code is Luau for Roblox Studio. Send this to a dev who's building a shop. #robloxdev #robloxstudio #luau #roblox #gamedev
