Physics changes in 3.3
We encountered lot of issues, after migrating from 2.6 to 3.3. Most of these issues were related to physics. We were not getting proper collision callbacks. After some experiments, we found out that, every time the parent changes, the callbacks stop working. Is it a bug? or optmization of some sort?.
If it is a optmization method, can we get a callback when we change the parent?
Just for further reference, it is NEVER a good idea upgrading Unity in the middel of a project I$$anonymous$$O, since it can cause a lot of problems just like yours.
