investigate inventory slot locking

Escapee fixed with a PR here
#65

Last time I was messing around with it, there were cases where the fragment slots weren't locked, might need more investigation. The merged PR fixes the part about unlocking the slots when they no longer have fragments, which was a separate issue; might still be more to do here but will be closed for now.
Thanks for the PR!
