Talking Restart aeroelastic dual-time-stepping simulation problem

Hello,
I am running a, unsteady transonic NACA64A010 aeroelastic calculation in SU2 7.0.8.
I am attaching my .cfg file and the .su2 file can be found at

https://raw.githubusercontent.com/su...hybrid_inv.su2

I want to run the simulation and then restart it from the last computed timestep (999). Since I am running in dual-time-stepping 2nd order, I have to rename the last 3 timesteps from "restart_flow....dat" to "solution_flow...dat", but I have two problems:

1) if I provide only the "solution_flow...dat" files, the program will ask me also for the "solution_flow...csv" files. If I give both the .csv and the .dat, this problem seems to disappear

2) even if problem 1 seems to be solved, the restarted solution is not working properly, see figure.

I restart the file as described in the User Guide on GitHub (https://su2code.github.io/docs_v7/Restart-File/) , but something is not working properly.

Could you please help me?

Thank you in advance

The aeroelastic implementation never saves its state, and so it cannot restart properly.
Unfortunately the original author is not around to maintain that feature.
