I'm at level 15 and I don't remember expansions taking two days. Does the time increase the more you expand or did the expansion time just increase across the board?
Also, when I first tried this latest expansion this morning it said I needed 4 permits total. I requested the permits from neighbors and then this afternoon after I received all 4 permits I went to expand and it said I had 4 of the 8 necessary permits. It seems to have increased after I put in the requests. Was this some "update" TL did or a glitch?
