Stage C fix in 1.6.3 is incomplete. Whenever I change amount of cheerleaders in stage C faster spawn, I stop gaining pixels/destroying blocks and start to lose HP again.
OK, I will do that in few hours, but I would like to emphasize that its not serious bug. It doesnt prevent me from finishing stage C levels, I am just clearing them at slower rate than I would like (I already finished 100 levels of all stages except stage C, which is at level 92).
If I change amount of cheerleaders on stage C faster spawn (definitely when I increase number of cheerleaders, probably also when I decrease, but I am less sure), then I completely stop destroying blocks and start losing HP, but after I lose all HP and level resets with higher HP, everything works properly again, so I just stopped messing around with stage C faster spawn and keep it at 50%.
