What is the usual cause(s) the will trigger the warning, “The model state is currently marked as unrepeatable, meaning that you cannot recreate the state using the input record or data files”?
Common reasons are that there are some manual operations, e.g., extruder or building-block operations, or, some commands are manually input from the console window.
Manual input of commands will not cause the unrepeatable warning.
Most often this is caused by setting python-reset-state to false (meaning the python state is not reset on MODEL NEW, which means the model state is not guaranteed to be repeatable).
It is also caused by interrupting a command or FISH execution before it is completed with an ESC key.
