Ice in Ice Queen Domain should be thicker
It makes no sense, that in the land of eternal cold you see the same thin ice that breaks under just 2000s of weight. This should be some kind of thick ice, either unbreaking at all (because even one meter of ice is enough to withstand heavy trucks) or breaking under extreme load (50000s?).
Extreme cold that is enough to damage your equipment, but not enough to freeze thick ice layer or freeze open water after ice breaking? Completely unrealistic.
