Problem with weapon fusion

I have fused a gs into another gs ! after 1/2 minuts i logged off and after 4/5 minuts i logged in ! the fused gs has gone ! fortunatly i still have the first one ( the one that is not destroyed with weapon fuse ) but this one is normal , is not fused , it doesn't give me more stats ! is as it was before the fuse , and the other weapon has gone ! i can either put the weapon in the account werehouse ! I am not asking " oooh pls gm give me the lost gs and some candy " i just want to report this and maybe to know if tomorrow , when i wake up , my gs will be as it should be inched:
