Problem with LTspice simulation model on latest update

I'm teaching analogue electronics at a university in Norway, and I have been using LT1576 for an example design exercise in class. Simulation in LTspice has usually been quite close to the calculations. But this year the simulation is way off. It looks like the model of LT1576 is drawing a continuous current of close to 500mA from the input supply. You can check it by looking at the current through the ground terminal. Needless to say, my arguments on the improvement in efficiency compared to an linear regulator did not have the same punch this year. Can someone at Analog please have a look at what has happened. It must have something to do with the latest version of the software, because I have used the exact same simulation file as previous years.

I'm currently using LTspice (x64) version 24.0.10
