[2.0.14] Crash with non-blocking save, normal works (TargetSerialiser::clearSavingIndexes())

[joshinils]

a autosave crashed in the background.
my game did not crash, i just got the notice that it did not autosave.

I then tried to manually save the game, which also did not work. I looked at the log, which said it tried to save non-blocking both times.

I disabled the non-blocking saving option via "the rest" settings, and tried to save, which succeeded and is attached to this.

enabling the non-blocking option again (i believe without unpausing) and saving again worked (i named that "saving_crashed_test").
