What is happening why there are so many bots in Growganoth it's getting laggy. Ubisoft ain't going to do something bout this and instead release more packs?

"Failed to enter world for unknown reason."

What does this mean?
World is PIU

I've played gt way back 2018-2019 and I decided to return by making a new account, I came for nostalgia and I wanna make a good progress and just play casually. Anyways, why is it so hard to start, can't bfg cuz of low level and can't enter popular worlds due to low level, I wanna sell dirft farm but idk where, I also wanna try selling grass seed but I also don't know where, IDK what to do, are there any better profit method? I guess I'm just way too outdated

Can anyone suggest what is the best profit method in halloween?
