I would try running without PressTestEngine, just with TranslationEngine
instead (fixed number of steps).

You have bunch of state variables in PressTestEngine that are not saved
-- that is wrong. You should save (i.e. serialize) all state that is
needed to resume the simulation at any point (more or less, unless you
know what you do). For instace, minimalForce will be non-zero after
first 2 steps, but if you save and reload (in the same run or next time
you start yade), it will be initialized to zero and your engine will
behave differently.
