I am running a pimpleFoam simulation. But at a certain time step when it reaches a a convergence, it restarts from time 0 again, and not progressing.

I am attaching the controlDict and 0.p here. But do let me know if you need anything else to better understand what's going on.

I just found out that if I do a scaling of the geometry by transformPoints "scale=(...)", then this is happening. Is it wrong to do scaling this way?
