Yeah, I typically do restart immediately (Although I like to kill everything in the immediate area so I don't get a nasty surprise of several points of damage) because I don't want to end up losing my save file or anything.
Yeah, I've encountered three errors so far. The first one I think was many versions ago, so maybe that's part of why it looks weird. The other errors are a bit similar to errors in games like Terraria, but the difference is in that game, the entire game just crashes and there's about a 50/50 shot of actually making the error report. The thing is, I was certain it's got to be something wrong with my computer, or possibly with the game's files. If other people were encountering the issue I'd figure I'd be seeing a lot of those reports plus an immediate fix by you if it were at all possible. I've... stalked your changelogs on occasion, seeing fixes on an update before I even realize there was an update in the first place...
But yes, I need to check out maybe some virus scanners. I think there might be a hardware issue, but I don't know what kind of hardware issue might cause problems like these anyway.
Would just attaching my current save be reasonable? I mean, it seems random that something like this comes up anyway. It could take an hour of play, or days, or it would possibly just not come up at all. I'll just toss the file up for now, and maybe spend today playing until there's some kind of issue and immediately quit and put up that save file, to be more specific.
