I need help with this potential bug, I really do not want to restart my game again, even more so when that may not even fix this problem.
Anyways, on to my problem! All the sudden I can't use items that I had researched. It first started with just one item, but now I can't use 2 items form the same category. I just used these 2 items to build a jet and I flew it. I went to go build a better jet and I couldn't find the air intake. So I loaded my old jet up and even though it has the intake it says in red letters *** CONTAINS LOCKED OR INVALID PARTS***. When I try to fly the jet it does not let me (because of the parts).
Things I've tried to do, for a fix - Verify integrity of game cache (through steam) When doing this it says "1 files failed to validate and will be reacquired."
I also loaded an old saved file, this save file happened to be the one I used when I first flew my jet with no problem, and it still gives me the same message when i try to fly it.
I uninstalled the game (kept my saved files) reinstalled it, and still getting the same message.
I googled it for an hour and found nothing.
And yes I went back to make 100 % sure the 2 parts were still in the same place on the tec tree, and sure enough they are still under aviation, and its still unlocked, I can use all the other parts under aviation. On a side note, there are 38 copies of the Mk1 cockpit for whatever reason. I don't think it was like that before.
The two parts that I can't use are Delta-Deluxe winglet and XM-G50Radial Air intake.
Any help would be great, I feel like playing anymore of this could be a waste of time if I can't use the things I unlock. Sadly, that means I'm not going to play until this is sorted out . (sucks cuzz I really wanna play)
After typing this I also went back and checked sandbox mode, sure enough the same parts are grayed out and I can't even select them, there are more parts that I can't use in sandbox mode.
A fix for this problem would be amazing! Thanks
