I've noticed that hireds don't have the timer on howmany hours you have left in your shop. It's useful to know when you need to reset your shop.
Normally, shops close after 24 hours. All shops are closed when the server goes down though. As for when to reset your shop, I just leave a note of when I put it up.
I think for balance reasons it is nice to not have a timer. If there is, people will just hog their good spot. Getting FM spots near the bottom row of FM is already quite competitive, and with the growing number of shops that are filling in even on the third row in the rooms in Free Market, I would not be surprised if people openly start selling their FM spots for others to get more exposure, similar to the trend of how people are buying Ghost Ship 2 Maps now.
Selling fm spots/maps should be forbidden anyways. And why is people hogging an fm spot a bad thing anyways? It has been done since always.
Unnecessary extra work for the developers when you can just simply put in the small effort on your side to make a mental note.
People are buying GS2 Maps now???!? The FM being fiercely competitive is one thing, but I'm disgusted to hear that people are actually selling grinding spots. -_-
This morning someone was trying to sell it for 10m and then 8m. I honestly think selling map spots shouldent be allowed.-.-
