Hi Sun-Tun,
You don't have to understand our priorities. Developers have their to do lists and we handle the priorities of to do lists in linked to many parameters.
However you are welcome to constructively report any issue or feedback to be sure that the team is aware of this issue.
We received many feedback from our alpha testers but it's always good to have reports or feedback from different kind of players.
Some players prefer building tacks, items, other one developing things, other ones competing, running servers or rooms and other ones prefer racing, winning trophies or playing with friends or family. Players have different interests when connecting to the game and having reports from different type of players is always rich for the team.
Happy Day!
