Problem Description: After updating AMP, no matter what I do I cannot get online-mode to change to anything but true. I switch back and forth regularly for a variety of reasons and no longer can. Other changes to the files save, except this one. It is almost as if this specific string is being blocked now.
Actions taken to resolve so far: Tried editing server.properties in and outside of program. Tried importing, tried copying over from a backup. Tried changing the option in MinecraftModule.kvp to Minecraft.Offline=true.
Just a general note, online-mode=false is only supported for Proxy server setups.
As mentioned in the update notes, there is a new option under Server Settings called Standalone Server that now handles this.
