Had issues after removing a mod (Quiztech Aero, FWIW) referenced in both completed and potential (but not active) part-test contracts.
Log throws:

Contract: Exception while OnLoad() or SetupID() on contract Test Part landed at Kerbin., exception System.NullReferenceException: Object reference not set to an instance of an object
at Contracts.Parameters.PartTest.GetHashString () [0x00000] in <filename unknown>:0

Followed by:

And I can not enter / exit buildings.
Removing all mention of offending parts from save file has fixed it, just a FYI. Can probably repro w/save complete log etc. if needed.

Was considering repro with more info, but with 1.2 almost here may be better left until I can test in the new release?
Ping me if you want me to go ahead anyway in 1.1.3.
