Hey Alex, this is still a problem for me. Game is running, I hit edit to watch the FSM run and check variables etc, it just says disabled.
Here's what i've found on this. If the game is running, you select a prefab, and the first/highest FSM displays propertly (even if it's a template). It is being "viewed". BUT if the prefab has a few FSMs, you have to hit "edit" to view ones beneath the first. When you hit edit, it just shows it as disabled. It doesn't default to "view mode" like you describe above if the game is running.
HELP!
