Has something gone wrong with the mod ?
You don't like the music ?
That is supposed to be relaxing, Gleba is the planet of plant, and plant relaxes me, if it doesn't relax you and you prefer something funny, i can recommend this other mod i made https://mods.factorio.com/mod/PI-Lyrical-songs because the songs have lyrics which are intended to be funny or this other one which contans funny quotes with different flavor of funny : https://mods.factorio.com/mod/Robotic-Voice-Sample-For-Speaker, or maybe this one which will make yumako sound funny ? the most flavorish https://mods.factorio.com/mod/Eatable-Sound-Effect
My 2 friends found it funny, but they don't go outside either, so none of us are aware of what's the funny outside the rehab center, feel free to forward some references !
