Weird SPH parts issues

[transmothra]

I came across a couple of weird issues and haven't had much luck finding information online or here. Here's some brief descriptions and screenshots.

Level 2 SPH unlocked; unable to use more than 30 parts out of 255:

'Landing' science node unlocked; many many iterations of LY-10 retractable landing gear:

...yet part is not available for use:

This of course is in combination with the classic save file issue, which means every time i have a crash (at least once every few hours), i'm reverted back to an earlier point anyway. However, i've reverted back before to this point and at least the 30/255 max parts issue seems to be sticking around. Also, planes are nearly impossible in career mode, but that's been discussed already. Just venting.

UPDATE: i just managed to land within a day's walk of a target to do an EVA report on Kerbin, and after walking about an hour (gametime, time warp x4), I FELL THROUGH THE LANDSCAPE into an endless sea below. Come on!!

My R&D Screen "Landing" is also filled with LY-10 

All grey except the last is white.

Same name but half info text and some stats are different.
