If your maximum HP (with or without Navicust/Mods) is a certain amount and you finish/quit a Liberation Mission, you get plugged out with Rockman not in your PET... Kinda. You can no longer plug in afterwards, resulting your game to be deadlocked unless you sent it to Capcom or start a new game. This was fixed in international versions.
