MC launcher update pushed to my machine yesterday, and suddenly my Spigot server is bungeeing like crazy. Blocks I just mined suddenly reappear, I'm repeatedly bounced a few blocks back from my most recent position, lag mid-draw or mid-strike means I am often missing targets with arrows or hitting a block I had not intended to break. Log on the server doesn't show anything except a couple of commands I issued while playing - no "moved too quickly!" alerts at all, but that's what it is acting like. Anyone else seeing this? I rebuilt Spigot right before the new launcher downloaded, so I'm not sure if it's the server build or the launcher... it's really annoying, to the point where it's difficult to play. Server load didn't crack 10% when running so I am suspecting it's a launcher issue.
