I've been the culpret of this about a half dozen times. I apologize if this has already been noted or if i posted it on the wrong forum but i do think this is a problem not yet discussed. If a person fires a beam, and another person does a last minute counter beam, you will take damge and get in a PS, but at the same time it crashes servers, i thought it was just one server but it appears it Always crashes servers, and I tried it with a bot and that happened also. (the crash that is) Also about the disk issue since i haven't seen the specifics i will let people know, after multiple trial and errors it seams "Maxing" a Disk crashes servers, still doing research on the Gohan Shield i can't find anything that is constant. but the crashing seems to result from high powered beams, and the ammount of charging on the shield but i will give more information later.
