Physics tanks after upgrading from 5.2->5.6

I upgraded the engine so I could use state trees for my AI. My RTS units use physics for movement (AddForce and AddTorque), which worked without issue in 5.2. Now even with one unit moving on an empty map, the MoveComponent(Primitive) Time in game stats will continue to increase until the unit comes to a complete stop, and the stat returns to the idle level. In the physics stat, the SyncBodies time increases at the same rate.

It seems there were some big “improvements” to chaos physics in 5.6, so I am wondering if I had something setup in 5.2 that simply doesn’t work correctly in 5.6 :man_shrugging: Anyone know where I should start?
