Yes- it's that time of year! The time of the year when there are weird bugs...

I have a great idea, I haven't a LOT done but im positive i will be able to finish the game. However, I'm bumping into some gambreaking bugs for no apparent reason. I'm using Unity3Ds built in "OnTriggerStay2D" and it works for like 1 sec but then the method stops getting called- in two objects inside each other that aren't moving. If i make one of the object vibrate everything works, but that's not very elegant now is it?

Does anyone have a solution to this :( ?
