Hey Cycerin, I've been playing your faction more and the Imaginos, and I have not been experiencing any more crashes with the Scalar Deracinator, though I haven't used the Karkinos' deracinator in awhile.
In other news...
Rather than playing Exerelin, I've switched to Uomoz's Sector: Journey 1.1 in the meantime, which has Blackrock Drive Yards as a faction in it. I'm not entirely sure if this is a problem unique to the Uomoz mod collection, the Imaginos has been having consistent scalar deracinator feedback issues. The screenshot included above is the aftermath of a scalar deracinator use that put the frigate within about 200 range of the fighter. For whatever reason, there seems to be a feedback whenever the frigate teleports close to something. I'm not sure if this is intended or not, but there's not a completely discernible pattern to it. While it only happens when I teleport close enough to a ship to damage it with the scalar deracinator, it does not always happen no matter how far or close to the ship I teleport to. In fact, just after making that screenshot I got into another battle and ended up not having ANY scalar deracinator feedback against fighters and larger ships.
I believe the pattern is that some battles will always cause feedback if you teleport too close, and other battles won't cause them at all. Er... I don't know. Just curious is all, I guess.
