We noticed a lot of people still use the kitserver incorrectly.
You are supposed to select the kits through the sider console, here are the steps:
During kit selection:
1. Press "space" on your keyboard to open the sider console
2. Press "1" on your keyboard until you get to "kserv.lua"
3. Switch the kits by pressing "6" for home team and "7" for the away team
4. NEW: in UML v2 now you can also switch between alternative combinations of kits (different shorts/socks colors) by pressing "4" for home team and "5" for the away team (not all kits have alternative options)
WARNING!: DO NOT mix UML kitserver with another kitserver. All you're going to do is create issues like missing numbers on kits and other kit related issues. Always follow the install instructions that we include and delete the mentioned folders before installing the new UML update.
