Yikes, the Vapor ships gave me a mild scare when I first encountered Diable fleets recently. For a moment I thought I hit a glitch/bug of the mod and so far I'm not sure if it is intended or not.
Right now the Vapor-class so far has a very sever case of some teleporting seizure and panicking PTSD attack disorder having trainwreck that flee from battle the moment I point my ship's front end along with my [REDACTED] LPCs at them and the rest is basically witnessing some demonic possession rituals phasing and teleporting away near to the borders of the battle mode. My face looked literally like this when I first witnessed it:
Have not used or tested the Vapor ship myself since I prefer flying fast destroyers, carriers or cruisers instead for obvious bigger weaponry arsenal.
Not really that much of a big deal to me as it is in its own way from amusing to hysterical as in replace the word "Vapor-class" With "Seizure-class".
Then again, last time I used the mod I didn't go against majority of their ships as I started out as part of them or made them as allies and so I avoided hostilities with them.
