Are you experiencing the error message [Wurst] [ERROR] Unknown command: .dupe while using the Wurst Client in Minecraft? This article will help you understand why you're running into this error and what you can do to fix it.
It may seem like the Wurst Client's .dupe command is not working, but this is not the case. It is simply a matter of using the right versions of Minecraft and Wurst itself.
The error message [Wurst] [ERROR] Unknown command: .dupe occurs when you try to use the .dupe command in a Wurst Client version that does not support this command. The .dupe command exists only in Wurst versions for Minecraft 1.16.3 - 1.17. It was patched in Minecraft 1.17.1 and subsequently removed from Wurst Client versions that target Minecraft 1.17.1 and later versions.
If you try using the .dupe command while playing on Minecraft 1.17.1 or a later version, you will most likely encounter this error message.
The .dupe command is available in Wurst Client versions that target Minecraft 1.16.3, 1.16.4, 1.16.5, and 1.17. It also works with a couple of old snapshot versions. However, due to the command being patched in Minecraft 1.17.1, Wurst Client removed the .dupe command from its versions targeting Minecraft 1.17.1 and later.
That means the .dupe command is still included in the following Wurst Client versions:
| Wurst Version | Minecraft Versions | Snapshot Versions |
|---|---|---|
| Wurst 7.14 | 1.16.5, 1.16.4 | 21w15a, 21w14a, 21w13a, 21w11a, 21w05a/b |
| Wurst 7.15 | 1.16.5, 1.16.4, 1.16.3 | 21w19a, 21w18a, 21w17a, 21w16a, 21w15a |
| Wurst 7.15.1 | 1.16.5, 1.16.4, 1.16.3 | 21w20a, 21w19a |
| Wurst 7.15.2 | 1.17, 1.16.5, 1.16.4, 1.16.3 | 21w20a, 1.17-pre5, 1.17-pre4, 1.17-pre3, 1.17-pre2, 1.17-pre1, 1.17-rc2, 1.17-rc1 |
| Wurst 7.27.3 | 1.16.5 | |
| Wurst 7.31 | 1.16.5 |
If you encounter the error message [Wurst] [ERROR] Unknown command: .dupe, there are a few steps you can take:
Unfortunately, no. The removal of the .dupe command from Wurst Client versions targeting Minecraft 1.17.1 and later was not a simple matter of “un-patching” or tweaking some code to make it work again. Minecraft 1.17.1 fixed the issue that made the .dupe' command possible, addressing the underlying problem that allowed this duplication exploit to work. This means that even if we were to add the .dupe command back, it would not work as intended on Minecraft 1.17.1 and later versions.
If you want to use the .dupe command, you will need to use a Wurst Client version targeting Minecraft 1.16.3 - 1.17 (as shown in the table above) and ensure that you are playing on a compatible Minecraft version. Keep in mind that downgrading your Minecraft version may affect your ability to play on certain servers and access some features or content introduced in newer versions.
