Undo not working in new practice drills.

[Affineer]

hi ,thanks for the update.

nice to see new features and improvements.

noticed one bug. can not undo shots in new practice drills (all round the black and crazy cannons), undo is working in old drills.

Undo is intentionally disabled for special lineups because they have their own leaderboard and record:

- Around The Black (ATB) and
- Tough Table Challenge (TTC)

Crazy Cannons is not special in this sense, undo should be working there.
