Im currently typing /cls create AssaultRifle 29. After that, i fill up my Large Wooden Crate (the one without any skin) with Assault Rifles. When i close the crate window, that message shows up. Someone can point what i am doing wrong?

Box id 29 doesn't work, neither does 4 and some others.
Some commands don't work and just give a console error.

As per k1lly0u standard, this is not maintained and NO support threads will ever be answered by the dev.
