Command XX is a MOD sequence (index).

In fact, you have made it very clear. If you copy the backup like this, you can succeed. If you haven't succeeded, I suggest you check if this is the same version as your game version. If you don't prove that this version is not suitable for you, you need to upgrade before you can use it. Generally, there are versions of games. What time is it? So this is very important, but sometimes there is no upgrade patch for this version, so you have to wait until the patch is officially released before upgrading. good luck
