Wrong version of Neoforge being installed #3701
Description
Describe the problem
After the little issues there were today, I am now facing a different one.
Whenever I start my container with NEOFORGE as the Server type and 21.1.208 as Forge Version, the server actually tries to install neoforge 21.1.1.
