When placing liquid lava on an ice block it doesn't melt.
How to reproduce
Start by filling a bucket with lava
Then freeze water and turn it into an ice block
Then pour the lava onto the ice block, its not gonna melt.
Update
Turns out I was using blue ice and not normal ice, blue ice doesn't melt but regular ice does.

Turns out I was using blue ice and not normal ice, blue ice doesn't melt but regular ice does. So this report is invalid. Thanks for informing me tryashtar
That's blue ice which doesn't melt
