two simultaneous retimer events result in position mismatch/offset

[tyFlow]

Well the retimer doesn't affect any colliders directly...likely what's happening is your retimer settings are at odds with the playback speed of whatever the "invisible" collider is (the collider you've added to the PhysX Collision operator). Ex: if your collider is the retimed hamburger, and you're also retiming the cheese after, the retiming is being doubled-up on the cheese relative to the hamburger.

You need to simulate everything at regular speed and then retime everything after, not sim #1, retime #1, sim #2, retime #2, etc.
