The Switch version is goosed…on that platform there are save editors that allow full save editing because the Nintendo Switch firmware has been hacked.
The developer of a game cant be expected to combat a platform issue.
You can’t expect a developer to include sanity checks for a game because the platform has been hacked.
Especially given D3 is just a port and not a full fledged Switch developed game.
Yes sanity checks would help but we have asked that since S10 when it came to consoles and they have never implemented it…it wont come now.
