Balls still magnetize even if it's color is removed

[ShamblesSM]

This bug is detrimental to gap shot strategies.

Suppose we have a track here:
🔴🟡🟡🟢🟢                    🟡

Matching the green spheres would cause the lone yellow sphere to slide back, as expected:
🔴🟡🟡                   🟡

However, adding a sphere that isn't of the same color won't prevent the lone yellow sphere from magnetizing further, even if there isn't any spheres to magnetize to. It will still magnetize, but at a constant, slower rate.
