Running sol = Earth4All.run_tltl_solution() does not produce the right result. There seems to be an issue with the initialisation.

retcode: InitialFailure

The following warnings appear:

┌ Warning: Independent variable t should be defined with @independent_variables t.
└ @ ModelingToolkit ~/.julia/packages/ModelingToolkit/eiNg3/src/utils.jl:119
┌ Warning: Initialization system is overdetermined. 50 equations for 3 unknowns. Initialization will default to using least squares.
