I've been using a script I found on the internet to measure the THD of amplifiers. It steps through specified frequencies or voltages. After the update to 24.1 all voltage stepped and all after the first or second frequency stepped measurements fail. I know very little about spice directives so I haven't been able to figure out what's wrong.

To replicate:
Download and extract http://www.audio-perfection.com/wp-content/uploads/THD_Analyzer.zip
Open Example_BJT_THD_TEST.asc and run the simulation
After the simulation's done open the spice output log.
In the previous version (24.0.12 I think) I used to be able to right click and "Plot .step'ed .meas data". In this version I get "Incoherent .measure data".
