there.
Mode switching resolved.
You're welcome FD!
Too many holes in your idea to be a practical solution, though I can't help but notice that you have the sack to come up with an idea to fix things while the majority of the forum (players who no doubt love the ens out of every exploit in the book) tell you all the reasons why you are dumb and you should just go away. So, plus one for being unlike all the people who've simply embraced cheating and exploiting the game.
Much better approach: when starting the game first time you will select what mode your cmdr will be playing FOREVER.
You want to switch modes? Clear your save. This way we wont have intentional undermining in SOLO and griefers wont be able to hide in solo when they murder in open.
Problem solved. Fdev lets go!
Ah, now we're cooking with gas. This idea has my endorsement.
