I made a funny joke, but ... I keep getting Tumble Checks when I have Spring Attack (which is required for Whirlwind -and- being a Weapons Master) ... I am not sure what is going on, but I have seen this issue multiple times... it's not "attacks of opportunity" (which can be triggered by drinking a potion, etc) ...
The issue is literally that a Tumble Check can only be triggered by moving around in combat ... and the 'Spring Attack' feat is supposed to prevent that from happening.
