I know how to replicate this glitch properly.I just found this a month ago but didn't have the time to report it.
Anyway,here's how to do it:
1.Place SCU on ground
2.When it's powered up fully,use the radial menu to return it to your inventory
3.Click undo,when it returns it will look like that.
Not sure if this helps in any reason,but here it is anyway...
I've just merged @Zorgomol's new thread titled "[188.8.131.52](PC) HE SCU visual glitch" with this older one.
It was already known a year ago and I've seen it continually since then with the GSO SCU. It's an animation glitch with all the SCU and crafting blocks that can animate - they glitch if they are unloaded from the world while deployed/animating, and the glitch transfers to any new block of that type that is instantiated.
I was only able to find this old report because I had it archived on my PC. Couldn't Google it and the forum's search function refuses to work with 3 letter terms like "SCU" (too short). @Matt could you get that restriction relaxed? I hit it a lot.
