Is there any link between the staff and the community whatsoever?
Tutors? CM's? GM's? Why are there only players in the game?
Why the staff only drops (sorta random) stuff in the game and doesn't participate in it in any other ways?

Not really.

They lie dormant for months, and in a miraculous blink they appear for a brief moment.

Today is the third day that we have found a huge bug in the in-game bank system. There have already been numerous reports and email. zero responses.

Play for fun, don't create expectations.

Theyre non-existing, its just a hobby project that brings a little money on the side.

Like Briareu says, just play for fun and dont expect anything from the dev.
If you play for updates sake, don't haha.

Its fun to make free money with these new duplicate bugs. We dont need to repair the market so quickly.

The bug is not a dupping bug, and you dont "make" money, you actually LOSE money at the bank. Its a very specific situation bug and you probably wont suffer from it.

Braireu: Why don't you write more about this market bug?

I'm really enjoying to play the game but, this distance from the staff feels sorta bad.. this is such a nice game and i think it could grow alot if the devs gave it a closer aproach

Nonono, let the rumors spread, and maybe they look into it.

Ps: its a bank bug, nothing related to market.
