The Ninjutsu talent that refunds weapon swap momentum when you swap into a shuriken - in actuality always refunds 3 momentum. Despite saying 'refunds the momentum,' if you swap your shuriken for a non shuriken, for 3m then swap that non shuriken for your shuriken for 4m, you'll be left with 3m instead of the 4m you just used.

Same for if you use a shifty pocket to swap something for a shuriken for free, swapping it back to the shuriken that round costs 4m and sets you to 6m instead of 7.

Not a bug. Shifty Pocket specifies that it will only restore up to 3 Momentum. Hayasa has been updated to also reflect this in its description.
