I was wrong, difficulty selection isn’t broken, but playtesting difficulty carries over to next hosted lobby if you don’t restart game
Changed title to Playtesting prior to hosting breaks difficulty selection for scenarios
How to repro this bug
Step 1: Playtest anything on editor in difficulty X.
Step 2: Without restarting game host any scenario on difficulty Y. It will default to difficulty X.
It isn’t as urgent as it seemed as it only affects anyone who uses the editor and has easy workaround.
