I'm not experienced in starsector modding enough to know who or what exactly, I think it may have been a file name colliding since to fix it it I had to rename the png and projectiles. Which is why I had trouble with the coil as it reuses some file from heavy mjolnir. OCD triggered in having different names for the same weapon so I went ahead and renamed everything.
The actual error in log was about loading files in other mods (underworld, but if I disable that then VIC, but if ...) and isolated to when supercapitals mod was activated the others loaded fine.
