This is a beta server (like most Fonline server)
Which mean they are still remaining bugs, especially after dev implement new features (which happened recently and happen quite often)
Also, the game is free and those who work on it aren't paid, so we shouldn't expect perfection.
Although i think there far less bugs than some AAA games that you pay 60$.
Still, don't hesitate to use the bug report section. It will help the dev to notice the bugs that bother you and they will fix them quicker.
Consider yourself as a player AND a beta tester, here to help the dev notice bugs and balance issues, while still having fun playing the half-finished game. (maybe more than half, but still, it is not complete yet)
