Incorrect display / Missing Wave

Hi All

Got a minor bug here. currently rank 290 and the attack i get is supposedly 4 waves according to the top right display.
However i never see the 4th wave and the attack ends once wave 3 is cleared. not sure if there should be 4 waves or the display in the top left is incorrect.

Cheers

oh. well jsut as i post that it appears to be back to normal and now displaying the 4th wave.
ignore this post
