That's an odd one but it's a false positive - heuristic detection can do that sometimes and it probably just doesn't like the fact that it's an unsigned executable. LCSXMLEditor.exe is a very basic winforms program that I wrote a while ago and should probably just remove because I haven't kept it up to date with the full set of XML tags the game actually uses. It never actually gets run by the main executable itself, it solely exists as an editor for messing with the game data files.
Aight.

Just had the zip re-analyzed, so it's getting a 0/61 now. 5 months ago, though, it had a threat detected on one of the security vendors. Don't recall what the detection was. 🤷🏿♂️
