I saw some guy say that Vibrarium Charging should exist, but there should also be a way to decharge it in some way. the post was https://powdertoy.co.uk/Discussions/Thread/View.html?Thread=28032
Essentially, this shouldn't happen because vibranium cannot convert negative temperature into negative TMP.
For me, VIBR discharges with VAC or COOL, but only after it has already been charged up with something else (e.g. HEAT).
