Bugfix: 129

Fix to issue #129, which expanded beyond the original psyche-lock only problems, and into general features of the save system that were supported in theory, but actually glitched.

About the state property... If we want to add a field to state, should it be in self of the relevant object, or is it acceptable to use a simple expression to get the value instead? (This has come in my trying to fix issue #50, preserving the text colour.)
