It was about GMT 7:20 that I flyed my capship into pelatus C12. I undocked behemoth XC, docked into that station and built 4 Fluid Formable Silksteel Alloy. However, when I undocked my XC and tried to dock into my capship, the FPS down to a low point then game crashed without showing any dialog about reporting bugs. And this happened for 4 times when I tried to dock into my capship with a undocked XC in pelatus C12. and this thing didn't happen before or in other sector. So I believe that it was a bug that needs to be fixed.
My laptop is Lenovo using windows 10.
