Hello!
I noticed that when you measure the temperature of other players using the thermometer, it displays the temperature normally in the place where the word "survivor" would appear on them. However, measuring the temperature yourself is bugged in such a way that I am not able to get an accurate reading for it. Instead, there appears a number on the thermometer that's part of the HUD that is either 0 or 1, either above or below the HUD element. I can't make any sense from it.
