I always thought the point is to check out that you are not doing some unpleasant thing in our computers with a "black box". But it doesn't really matter as I am using your binaries, not going to rebuild the dll's... If the bosses said nothing so far, I guess everything is fine. More important than that: I've found a nasty bug! Playing in Debian x64 there's an incompatibility with Kerbal Inventory System (KIS). You just cannot attach something to your Vessel, it is dropped as if you used the "drop" option instead of "attach" (x key) option. [LOG 01:28:49.997] [KIS] Move part & attach[LOG 01:28:49.997] [KIS] Attach type : Surface | ID : srfAttach [EXC 01:28:49.998] NullReferenceException: Object reference not set to an instance of an object OLDD.EventProcessor.OnPartCouple (FromToAction`2 action) EventData`1[GameEvents+FromToAction`2[Part,Part]].Fire (FromToAction`2 data) Part.Couple (.Part tgtPart) KIS.KIS_Shared.CouplePart (.Part srcPart, .Part tgtPart, System.String srcAttachNodeID, .AttachNode tgtAttachNode) KIS.KISAddonPickup.MoveAttach (.Part tgtPart, Vector3 pos, Quaternion rot, System.String srcAttachNodeID, .AttachNode tgtAttachNode) KIS.KISAddonPickup.OnPointerAction (PointerTarget pointerTarget, Vector3 pos, Quaternion rot, .Part tgtPart, System.String srcAttachNodeID, .AttachNode tgtAttachNode) KIS.KISAddonPointer.UpdatePointer () KIS.KISAddonPointer.Update () I may supply the full log and anything else if needed.
