Mine model update on test branch

Rust has received a major update on the test branch - the mine model. It now looks completely different and has even been renamed to "Improvised Mine" to reflect its new look. The older model has been completely removed from the game, and players will now be able to enjoy using this new and improved weapon. Model updates are an important part of the gameplay, and the Rust developers continue to work on improving the look and feel of the game's items. With this new mine model, the game becomes even more realistic and immersive. Be sure to check it out on the test branch and share your impressions!
