Fixing a plugin (False Gravity)

So I got this plugin called False Gravity made by Alex Davis used in his game Recursive Pain. It is the perfect plugin for my game but there is one problem: The Plugin bugs on sphere that means that at the bottom of the sphere the character spins like crazy and tends to change alone the direction (only bottom). If someone want to fix it I be really glad would even pay 10 euros if it is fixed.

Wouldn’t you find more support in…ne/marketplace forums? This place is only concerned with the coding part. You post the code, state the problem and get the solution. Simple! No monetary transactions are desired here (or maybe it is just me).
