I am using Farseer Engine3.5 and seeing an issue with objects colliding when they shouldn't be.
I have assigned each object-type a different collision category and set their CollidesWith property to the category of each object type they are supposed to collide.
This works for most of the time, but I am seeing collision between two objects that are not supposed to collide.
The debugger in CollisionCallBack shows the following values for two fixtures:
_collidesWith : Cat1 | Cat5 | Cat11
_collisionCategories : Cat4
_collidesWith : Cat2
_collisionCategories : Cat7
The collision group for both these fixtures show up as 0.
Can anybody tell me a reason why they might be colliding
