* Add 1 Part 57029c01 Black Projectile Launcher, Cannon, Flat Bottom (Alternate) (match ID 6)
* Change 1 Part Black 32074c01 Projectile Launcher, Cannon, Round Bottom {match ID 0 to 6}
Comments from Submitter:
A new/sealed set that I opened included the projectile launcher with a flat bottom instead of rounded.
