Instead, it tends to turn into water at closer to 97.85C.

Water starts turning into water vapor at 97.85° C, I have noticed this just by messing with uranium and water. So I highly believe it's intentional, not a bug.
When I first noticed it.
I was two numbers off, dang it! But I think it works even if it is a bug.
NUCLEAR FOX: did you know there is a hidden element called "Steam train?" It's a gas that moves back and forth in a straight line and emits an endless supply of smoke. The fact that that your save is called "Steam train" made me think of that. Isn't that something? *chuckles*
