That glitch can cause the entire game crash or get stuck and cannot be able to recover any save (the actual and the preivious) So, it was mandatory to fix it, sorry for the inconvence, maybe I will add that "new game+" when I finish it.
Oh my, I never experienced that thankfully, but I can certainly see why it was patched. No need to apologize though, I shouldn't be the one to dictate how the game works. Good on you for fixing such a potentially catastrophic bug, hopefully it could work out as a feature some day but that's not my call. I greatly appreciate you taking the time to respond and wish you luck with further development!
