dunno if this will help or if it's even a thing, but i've been playing EXP branch a bit and 4 out of the last 5? spawns i've gotten sick pretty much instantly but this last run i changed up my routine and i've stayed healthy the entire time - i just took off running like a bat of hell to keep my temperature up after i spawned, prioritized finding any and all necessary clothing, and stayed dry pretty much the entire time, even when it started raining i made sure to stay dry by staying indoors and lighting fires, haven't been sick yet
