Please be specific with version numbers. Did you file an upstream bug already?
Do you mean https://github.com/BZFlag-Dev/bzflag ? Thats c++ and must be compiled with zig c++.
Ah, well, it must have been zig c++, then, necessarily.
Was I planning to file an upstream bug? I was unaware.
I did contact them about it, actually, but it wasn't solved at the time.
