SCAN updates without checking the version of the game.
It is necessary to verify all mods at the appropriate version KSP.
In my case(KSP 1.0.5) broke mod:
DMagicScienceAnimate-v0.12 downgrade to v0.11
USITools-0.7.1.0 downgrade to 0.6.3.0
(Both breaking research menu)
DeadlyReentry-v7.3.2 - break KIS. downgrade to 7.3.1
Also replace ModuleManager.2.6.20.dll to ModuleManager.2.6.18.dll (but about this not sure)
