HELP! massive craft suddenly has blocks i can't move/highlight

[praise the suuun]

im close to completing a replica Thunderbird 2 in KSP 0.24.2. just today i start up the game and some of the metal plates cant be moved. they're frozen in place and nothing can be placed on them. nothing changed obviously from 32 - 64 bit.

i think it started to happen after i hit 2000 parts. (well its more like 4000 because half of it is welded into one part; the pod. this could jeopardize my work of one year.

im confident none of my mods are causing this because i haven't changed my installation in months. it could always be the case though if there is no actual part limit for the SPH.

the strange thing is only the parts that have been placed really recently, in the last few days, are immoveable. the previous parts are fine and dandy. im even running the hangar at 20 fps with all these parts!

i think my saved craft file hit the limit of available size. how can i hack the game to allow an unlimited craft file size?

please i need to know why this is happening in the hangar. i cant just bin this project i have too much at stake!

i did some testing and i dont exactly have a scientific method but i tried deleting large amounts of parts without saving. i noticed some of the invincible blocks came back immediately! not all of the invincible blocks came back. im guessing this game has been written so that the more powerful the pc, the more parts that are loaded fully. (who bloody knows.)

what im gonna try tomorrow is saving the dead zone to a subassembly, finishing it as a new craft then gluing it back. if that doesnt work ill need a better computer.

anyone know what i need to edit in the game to take this limit off?

[another update]

tried the craft, with the bare minimum mods needed for it to function, in a fresh copy of ksp 0.25 (stoneage pls): no change to phenomena.
