Boat in Snow Bugs and Crashes Game

The first time this happened, I was using a boat in the snowy plains. The ground had snow, with some patches of dirt blocks or dirt paths. When I entered the boat, I started sinking underneath it. I quickly got out to avoid dying, and the boat disappeared.

I then tried to reproduce the bug. I crafted a new boat, exactly like the first one, and started recording. This time, after several attempts, I encountered a bug—but not the same one. Instead, the game crashed.

I have two videos:

• The first one ended abruptly because of the crash (screenshot attached, sorry, it's in Portuguese).
• In the second video, after restarting the game, I spawned exactly where the first boat had disappeared.

I attempted to reproduce the bug again but was unable to.
