RoninFrog Posted October 2 Share Posted October 2 I'm playing stock KSP. I filtered by tech level 6 and saw this weird looking twitch engine in the parts list. It's got almost exactly the same stats except slightly more mass and slightly worse atmospheric efficiency. What's up with that?? Quote Link to comment Share on other sites More sharing options...
Mr. Kerbin Posted October 2 Share Posted October 2 I think that's the old twitch model. Why it's there, I don't know. Quote Link to comment Share on other sites More sharing options...
GluttonyReaper Posted October 3 Share Posted October 3 (edited) Yeah that's the old Twitch! It got a replaced a while back... and looking at the wiki, it seems like they adjusted the stats as well at the same time. More than likely it's still there for backwards compatibility reasons - anything that was changed post 1.0 that was substantial enough to warrant a whole new part rather than just a reskin has the old version still around so you can still load old saves with those in use without issues. The same is true of the old Mk1-2 command pod and probably a few others. Obviously you can't normally see them... but I think they've just been removed from the default categories. When you use the filters, they filter through all parts, new and old. Edited October 3 by GluttonyReaper Quote Link to comment Share on other sites More sharing options...

Despite still existing in game files (and still usable with enough game file editing), if you load a craft with this part, it will not load. It will say the part does not exist or it can’t load.

That is weird... the Mk1-2 in particular was part of the first batch of (rocket) revamp parts, and looking at the changelog they were apparently intended to be deprecated at some point. I wonder if any of the other parts replaced in that update (the old decouplers, fuel tanks, etc.) survived? Quote Link to comment Share on other sites More sharing options...

If you look at GameData > Squad > zDeprecated > Parts > Command, you can see the old MK1-2 pods' files. You can also find the other removed parts there.

Iapetus7342 Posted October 4 Share Posted October 4 Very late to this but this is the old Twitch engine, which got a remake recently. You can also find the old MK1, MK1-3 and MK2 Lander Can pods if you look around Quote Link to comment Share on other sites More sharing options...

RoninFrog Posted October 4 Author Share Posted October 4 To avoid further potential conflict, here's the full list of old parts I could find through filters: Mk2 Lander can Twitch engine Illuminator Mk1 and Mk2 (no color settings) Twin boar (no flag) Probodobodyne HECS HG-5 Antenna (rotated) I don't believe there are any other old parts still included in the VAB/SPH. I also tried loading an old version of the Mk1-3 pod I downloaded off an old KerbalX craft and all the old parts that still loaded reverted to new versions.

Martian Emigrant Posted October 7 Share Posted October 7 Hi all. I once noticed after the MK1 command pod was changed that the old one was still available with a search. The reason I found at the time for that was that the training scenarios still used the old one. The old ships still had to load for them to run. Perhaps by looking at the scenarios we would find one that uses the old twitch. ME Quote Link to comment Share on other sites More sharing options...

You've found the old version of the engine, kept in the game and hidden so that the approx. 2 craft that used it still load in and work. I remember in older versions, you could even find the part used for naturally generated asteroids hidden in the advanced parts list. Quote Link to comment Share on other sites More sharing options...

Yeah, I was helping a friend on the console edition of KSP (1.10 iirc) and was kind of freaked out at that placeholder asteroid thing. The friend has thankfully since moved to PC edition but it's a weird thing to keep around in the editor. Quote Link to comment Share on other sites More sharing options...
