Issue: Crash Laying Network Cable
Crash (y/n): Y
Platform (Windows/Mac/Linux): Windows
Description:
So… was going through the tutorial. Placed my spawn point and then placed the Network-Bandwidth-Thingy (now known as NBT) next to it. Selected the network cable tool, clicked on the NDT and then the spawn point. Game froze up and then crashed after a couple of seconds.
Emailing you the log and save files now!
Thanks for the report, I’ve found the cause of this!
This is the most common crash report so far from MS15. It’s happening if you make a cable that’s too short; it’s accidentally making the cable with both ends at exactly the same position, and the rendering code doesn’t like that.
There’ll be a fix for this crash in an update in a few hours, plus a clarification in the tutorial which will hopefully help folks understand how network cable works a little more clearly. 
For the moment, you can work around the crash by building your network cables longer; long enough that a grey preview of the covered area draws around the cable.
