Seed "lost" crashes the game

I was remembering seeds from around the time of when I started Minecraft, and I remembered the seed "lost". I loaded the seed up in 1.13.2 to see how the seed had changed with new world generation and all. Instead of seeing a nice reminder of 1.4.7, I got a crash report. I tried the seed in 18w48b to no avail. I am confused on what is happening here.

how to recreate:

make a new world with the seed "lost" (without the quotation marks)

wait for it to load.

tadaa you get a java error message.
