Most item duplication glitches in Roblox history rely on network lag or desynchronization between the client (your computer) and the server (Roblox). Typical methods include:

Instantly teleports to and breaks iron, gold, or crystallized iron nodes across the public islands.

Third, even legitimate executors can quickly become obsolete. Roblox releases frequent security patches that break existing executors, forcing users to constantly hunt for new, often even less trustworthy, versions.
