my biggest accident was time traveling forward and losing flurry and rosie.
i'm almost done cycling back out for flurry though and I've been debating if I want to do the same for rosie.
another accident was having a full locker of spoiled turnips lol. :c
2 mil of spoiled turnips...losing 4 dreamies (Diana, Charlise, Genji and Fang :c) but 50 move outs later they're all back!
Don't be impatient and not talk to every single villager, kids...
While TT'ing for Halloween cause I had forgotten to do it I lost my then favorite villager Kyle, but luckily he was swiftly replaced by Julian who I keep a tight grasp on now!
Mine would actually be by not time-traveling...! Shortly after I first started, I took a long hiatus due to travel. I wrote down what date I'd last played, but when I started up the game, I decided to just load it up and accept the consequences... Cookie was gone, and I've really bummed ever since!
No real accident as in something got lost/destroyed, but I didn't have time for the harvest festival 2013 so I wanted to play it a day in advance, but somehow set the year back to 2012... Took me a real life week to fix that.^^;
Bam left me he didn't even tell me he just sent me a letter and his pic (that I have like 4 of) and Eloise left the same way a couple TTing days later ;~;
I was trying to speed up making gold roses and I was going to tt 1 day ahead. Somehow it ended up being 1 year ahead and all my flowers had died. My town had been wall to wall flowers/hybrids so I was in shock. Rule number 1 for tting: Never tt when you are tired.
I try to be really careful.
I freeze time - always use the system clock to change the time back to sometime after I last played - one time I forgot to take a note of the save, went back in time by an hour or so - and lost my turnips - only 400 & used them for flies/ants.
As I'm changing time every time I play I have a set routine to try and stop this happening. No doubt at some point I'll do it again.
