Hallo zusammen!

Ich habe mir einen größeren Surface Miner auf dem erdänlichen Planeten gebaut. Diesen mit einem kleinem Landedeck ausgestattet damit ein Transportflieger die Erze abholen kann.

Nun docke ich mit den Fahrwerken und dem Verbinder an und wenn ich abdocken möchte crasht entweder das Game bzw. stürtzt der Server ab (Host hat das Spiel verlassen) wenn wir mit mehrern auf dem Server sind. Es handelt sich um einen Nitrado Server. Danach antwortet der Server nicht und muss neugestartet werden.

Hier findet ihr den Log des letzten Absturz in der Hoffnung, dass ihr mir ein paar Tipps oder Ratschläge geben könnt.
