Some people are still having issues with the ggpo beta, but if you are, you should probably move discussion to the Official Skullgirls discord since I don't think anyone checks here anymore?
Also if you are having issues,using the -ggposhowinfo feature and sending replays or getting a video, since it's easier for mike to look at potential issues that way.
Are you playing on switch? This looks like the switch glitches so I don't think anyone has gotten these on PC yet?
