Hi Scott, had a hard crash while playing this weekend and was able to replicate it easily. I'm not sure if the listed change I'm seeing in the 1.4.X blog post for "Fixed Co-Op abort issue" is my issue but it very likely could be. My issue however is after the abort when trying to start a new Co-Op game.
Here's the steps to replicate on 1.3.0:
1) Start a Co-Op game (I was using 4-person)
2) Progress to Player 1 Ball 2 and abort mission, letting all balls fully drain/reset position
3) Try to begin a new Co-Op mission
Upon pushing and holding the start button to begin a new Co-Op game the screen with flash (I believe) "Team VS Machine" for a split second before beginning a complete reset.
Hope this helps and thanks for the continued support...can't wait to see "HHP"!
