Output lag/ User defined config parameters how to?

Question 1:
I am currently running a fully connected architecture for 2D flow in a channel with a 2 element airfoil. I am running my script with 2 GPUs on a HPC. When I downloaded the output from the remote server, it seems that the output stops at around 07.43am. This below screenshot was taken at 03.43pm. Does anyone know if this is a server thing or a modulus thing? I am using modulus 23.08.

Question 2:
I am trying to define my own set of parameters in my config .yaml file. Correct me if I am wrong but Modulus only accepts known config keys defined in DefaultModulusConfig? Is there a way to add a user defined key in the config file? I got this error:
