Someone completed 2.5days or sth and I personally went all the way to Whate processing just for shits n giggles and still copleted in 3 days 3 hours(first try). You BS-caller, git gud. This is very basic challenge that's based on our daily TLD knowledge and some extra luck. If you put a clock on it majority of experienced(I'd say playtime 100+hrs) TLD players would complete this task within 5 days if you count some failures(due to wildlife attacks and such).
