... hmm...odd thread, a bunch of fucking badwordity badwords not being said 'round this joint.
But, on topic, the most common issue with import code is it doesn't account for a User that may be on a new system that doesn't have a proper export. Some VN's do handle this properly as they search to see if the data is available and valid before allowing an import option... but most devs just copy/paste bullshit from reddit or lemmasoft without any idea WTF is going on.
So, yes, there can be and is problems in a smaller percentage of folks... and my guess is this VN is absolutely no exception by looking at it's rather basic coding.
That's my two censt for what it's worth...which ain't much. Regards.
