disappeared

Hello ESF. I don't know if this is a my trouble, but a lot of servers are just disappear from the Server List. I'm an italian guy (and in Italy there are really bad connections in general. Mine particularly cause I live not very in a big city...) and I cannot play a lot of servers for high...

i fought a battle with 7 bots at kamis "white" room. After the bots and i reached a powerlevel about 350 000 000, my kame-hame-ha beam disappeared. I wasnt able to see the beam & explosion and the attack made no damage. the other beams worked as usually. i dont know if this is a specific problem...
