I replied to your email, no save corruptions or crashes in a long while for me, so it's probably safe to say what ever caused that was fixed by the most recent update.
I did however encounter a small issue with extra health obtained after killing bosses when on Jie.
Today when i loaded my save on a Jie play through after i had already defeated 2 bosses (the slave master and the ant queen). When i got into game Jie's health had reset to 3 (should be 5). It caused me no issues and i was able to beat the game anyways, so no skin off my back. But if it's not intentional you may want to look into it.
