I'm using JigLibX for a University project, games development.
Sometimes, PhysicsSystem.cs crashes on line 461, with the following notice:
ArgumentOutOfRangeException was unhandled
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
besides that, sometimes, also on afaik random moments, the speed of my player, which is keyboard controlled using ApplyWorldImpulse to generate speed on some 'natural' way, turns into Vector3(NaN,NaN,NaN). Although I can catch a NaN speed myself, there's no way to naturally restore the speed of my player, resulting in a standstill directly after such a 'crash'.
