OTOH, I think there's something wrong with PCS.
Because of the Shivan Comm Node Mantis report I've run FS debug three times. I've just started the game and gone to F3 lab, then I've selected Shivan Comm Node LOD0 and I've exited (actually the game crashes because of a
unknown known bug which Taylor knows about). Then I've read fs2_open.log.
When I use retail (from sparky_fs2.vp) Comm2s-01.pof I get the following warnings:
Warning: Ignoring unrecognized subsystem piece1a, believed to be in ship Comm2S-01.pof
Warning: Ignoring unrecognized subsystem piece2a, believed to be in ship Comm2S-01.pof
Warning: Ignoring unrecognized subsystem piece3a, believed to be in ship Comm2S-01.pof
Warning: Ignoring unrecognized subsystem piece4a, believed to be in ship Comm2S-01.pof
Warning: Ignoring unrecognized subsystem piece5a, believed to be in ship Comm2S-01.pof
Warning: Ignoring unrecognized subsystem core, believed to be in ship Comm2S-01.pof
When I use new Mediavps 3.6.10. Comm2s-01.pof:
Warning: Ignoring unrecognized subsystem piece1a, believed to be in ship Comm2S-01.pof
Warning: Ignoring unrecognized subsystem piece2a, believed to be in ship Comm2S-01.pof
Warning: Ignoring unrecognized subsystem piece3a, believed to be in ship Comm2S-01.pof
Warning: Ignoring unrecognized subsystem piece4a, believed to be in ship Comm2S-01.pof
Warning: Ignoring unrecognized subsystem piece5a, believed to be in ship Comm2S-01.pof
See how
subsystem core one is missing probably due to the Mantised issue, as core isn't likely a valid subsystem. The Mantised in-game warnings aren't shown when you just open the model in F3 Lab.
Then I open Mediavps 3.6.10. Comm2s-01.pof with PCS 2 (your latest build from 0112 at 22:50), I insert an Enter in the middle of the conflictive line and I save. Then I get:

See how
subsystem core is present again as it should be but now there are a lot of
Inverted bounding box warnings...

I upload an archive with the three models in case it can be useful. (Remember to fix the extension of the desired one)
