I can't even tell you how many times I've been happily sailing along through the ocean when BAM! I hit a squid and have to swim to an island hoping for a tree so I can make a new boat. /palmface
Same here. Boats are baaaaad.... I sailed into an ungenerated chunk. My boat literally just feel through the darkness and lag. All I could see was my hand. I logged off and came back on, and my boat floated up from the ocean bottom, only to break on hitting the surface. But really, boats aren't out to kill us! The real enemy is... beds! *Cues scary/evil music.*
