Retsam, nice catch.
I should of assumed there might be an issue with that, but I overlooked it when nothing crashed.
Needless to say, I fixed that issue with windows and also added better building support for both windows and linux in version 0.2.6. Hopefully, this will be the last update for awhile.
Edit: To update, you'll need to replace the gamedata file as well as the binary and restart your server.
