Title pretty much says it all. I spent all day making a sailboat (DAMN YOU, SCARCE COPPER FOR TOOLS) and finally finished it. It slid off the rollers and into the water, but I cannot get in. Whenever I try to enter, the sailboat bottom has no collision and I just fall into the water and am pushed away. I have tried spawning a new one in creative mode, same issue. What is happening?!
