Tried to model an equivalent circuit for a 3-phase TN-S system to model inrush behaveour. Was working for a while, and now nothing beyond the "Power Cable".
Probably an obvious reason, but unable to find it.. appreciate any help.

You probably had a .model card for your diode but deleted it? At any rate, you're using the default diode, without any settings, which means it's an ideal diode that has zero voltage drop and sharp knees in its transfer characteristics. If you'll add this to your schematic, it should work:
.model d d ron=10m roff=10meg vfwd=0.7 vrev=1k epsilon=0.1 revepsilon=50m
If, by any chance, you still have glitches, try adding some 1m...10m series resistance to the capacitors (right-click on the capacitors).
Be careful how you reference your nodes, because you have named the ground (zero, 0) net as both N and PE -- you won't be able to plot anything referenced to these names (i.e. V(L3,N) will not work).

\$\begingroup\$ Thanks, looks like using non-ideal diodes resolved the glitch. I was actually concerned about that when I drew the first rectifier bridge, but it worked for a while, so I forgot about it and kept using the standard ideal D model. \$\endgroup\$– MemorX86Commented Sep 10, 2020 at 21:07
