Don't Starve WARNING!

So I was on day 342 and had put tons of time into this game when it started crashing and now when I try to load my game back I get a blue screen that says:                                                                                WARNING! 

scripts/prefabs/shipwrecked.lua:503: attempt to call method 'Tropical' (a nil value)

LUA ERROR stack traceback:

Does this just mean all of the time and effort I put into this game is just wasted or is there a way to fix this. I put a seriously decent amount of hours into this game and if this bug just stole all of that progress from me I can't say I'll ever play this again which sucks because I genuinely enjoyed this game and don't want it to be ruined because of some bug. Anyways, if anyone knows what this means or a way to fix it I'd appreciate any response at all. Thanks, I really hope this gets fixed so it doesn't just ruin such a good game. PLEASE HELP!
