I have a strange result in a time dependent simulation using the AC/DC magnetic fields module. The solver seems to skip from step 67 to step 74, and the output jumps in a unrealistic way.

I've tried changint the relative tolerance and the tolerance factor in the time dependent solver node, and that has fixed it in the past, but the issue keeps coming back randomly as I change things in the model.

Any help would be appreciated. Attached is a screenshot and the model (solutions cleared for smaller upload).
