Play Offline fails with message: Error: Could not find or load main class net.minecraft.client.main.Main Launcher version 1.6.89-j Linux Mint 18.3 Open JDK 1.8.0_212 Minecraft 1.14.2 To clarify, the preceding error is what happens when I am offline, ie not connected to the internet. This is right after having successfully connected, update checked, logged in, played, a couple of minutes earlier Obviously, "Play Offline" should not require a network connection to Mojang.com.
