Apparent bug in GameTex?

[APCBoston]

GameTex is causing document compilation errors on Ubuntu 22.04 with MikTeX 22.8.28, example below. It appears MikTeX isn't correctly expanding the macro in GL2020.cls that defines the /latex directory.

Workaround is to edit gametex.sty lines 1677, 1684, and 1690 to remove /latex. As long as latex is called with the --include-directory command-line flag, it will work.

Filing this bug for future followup to figure out why it's borking.

It's possible that the "" in the \edef statement in _path.cls are the problem. Removing them seems to improve things on Ubuntu.
