I report and attach a craft file with which I encountered the same problems during the release procedures: suddenly the docking vehicle suddenly deorbits, or even during the approach they both explode once they reach a very close distance but without collision. and sometimes crashed. in the zip file, in addition to the craft file, I added the DXDIAG report. the game settings are low so as not to load too much video memory. It's not a blocking problem (I remedied it with rescues on mun :-D) but I think it can help understand any bugs. in general I am very satisfied with how the development is progressing and how the game is evolving. Greetings craft file & DXDIAG log on zip
