hey,

https://github.com/ezQuake/ezquake-source/issues/171
there is this thread where it is reported as issue on github. Its max_lightmaps in ezquake.
When you change it and recompile it it should work.

I used FTE to load it, but (not sure if intentional?) the first room is missing all textures (or is made without any, wtf) in the first tunnel?

Ah good to see I'm not alone and that it's highlighted, thanks!
