I was testing a minecart trap for noobs, where a detector rail would send a signal to a NOT gate, deactivating the piston which would pull the block out from under the minecart and sending the player falling too their doom in the void. I hopped in a minecart to test it, everything worked, I fell in the void and instead of dying from void, my game crashed. Minecarts with hoppers falling in the void also have this issue.
