When travelling to Caer Cyflen, I left my laptop for ~1 hour. Upon returning, the game showed the 'press any key to start' screen, and upon doing so then loaded the normal map of the party arriving in the city.
However a random encounter (bandits) overlay appeared and when I clicked on that to start the battle, it went to a loading screen, and after ~20 secs displayed 'error: data corruption' (the loading wheel was still turning but my curser was not visible) [https://drive.google.com/file/d/19PLQkn1j0eLeStqSGoABIU27z2IQcqIo/view?usp=sharing]. I then force quit.
Save file is autosave from end of previous travel encounter. https://drive.google.com/file/d/1o1JifizFPpzRWz3FrmzpWW84W6DTEE2W/view?usp=sharing
I have 'preserve random seed' enabled.
Upon reloading the game I ran through and the same bandit encounter appeared, and in-game time continued passing [https://drive.google.com/file/d/1l_QSPY8LXSRLpKVINjlALqnPZm-o7ECb/view?usp=sharing].
Save file from shortly before the bandit encounter appeared: https://drive.google.com/file/d/1JtZQZt2MSm-n0jeCgktWS4ZvmnuK8MnB/view?usp=sharing
After 15 mins I stopped waiting and started the encounter, which loaded fine.
