Which is abusable if youre doing this intentionally so you wont need the time to go back there nor need any escape ropes or w.e.

Found a bug while i was battling a pokemon and had to leave for a while i forgot to log out so i got logged out for being afk, when i logged back in i was in the pokecenter instead of e.g. dragons den where i was leveling before. Tried to log out while battling a pokemon and the result was the same. so when youre logging out while youre in battle youre going to be teleported to the next pokemon center. Didnt found anything like this mentioned in the forums, if there already is a topic about this - im sorry! Cheers, Cubo
