Game crashes in swamps and destroys my swamp key

yeah....game just freezes and i have to click on the close screen and then it teleports me back to my base without the swamp key in my inventory.

This is stupid since i used the ancient seeds to get a new key, went back to swamp and it crashed again and i lost the key.
When i reloaded the game i didnt have the swamp key or the ancient seeds.
This is a game breaking game and i could probably go in another swamp to see if it crashes but then what was the point of building my base near that particular swap?

so..your issue is losing your swamp key? or the crashing?
for the crashing it looks like your world seed generated some corrupted* part of the world hence when you get near it,it will crash the game
for the fix is go somewhere else/create a new world and move there

for the swamp key,if you are lazy i think you can use the cheat command to spawn item you lose

it's an area that connects a lot of land together. i would have to sail otherwise, really breaks my game. Seriously? create a new world? play 50-60 hours again?

Hmm, what's the command to spawn the key? its not listed in the guides i checked
