Ah sorry late response. I haven't heard of these bugs before, it might be a silly fix but have you tried playing the steam version? That one has had a lot more testing.
If you could pass me the error log just after you encountered one of these issues that would be great help! You can find it at "C:\Users\Eendhoorn\AppData\LocalLow\[user]\SpiritSphereDX\output_log.txt".
Thanks for letting me know!
