The overwriting issue with restarted computations

[春风复苏]

Hello everyone in the community, I ran a simulation for a while and finally obtained foo0.f00100. I then proceeded with the calculation and set startFrom = foo0.f00100 in the parameter file, without changing any other settings. However, the resulting output overwrote the previous foo0.f00001. What I actually want is for the results to start from foo0.f00101, otherwise I'll have to concatenate the files later, which is quite troublesome.
