Does not happen to me and my collection has more tracks (no baosting).
The easiest way could be to delete the library file as this has probably been damaged by the other terminations.
Could it be that your finding is a consequence to the behaviour described in this thread:
And a question on terms:
by "library" do you mean your collection of the library function as set in File>Options>Library.
And does this happen with the library function switched on or off?
