I just used the Playmods (CC/MK3/Military). I know that using them is unsupported , but I noticed that you cannot actually see the HSD option on the HUD. Moreover, I recognized that I have a CTD after sometime, when actually using the HSD. I'm not quiet sure about this, but I believe it only occurs after using the HSD. I also bought the artifacts from Galcom HQ and did not "mod" them in. I will try to start a new profile without buying the HSD maybe that helps with the CTD. Besides what's the amount limit for finances? PS: I really love this game..just went to Neptun to get some lighting ideas
