I've received this message about 3 times now in the past 5 minutes. This is usually after everything (butterflies, chickens, interactions with trees) starts freezing up as if there were extreme lag. Anyone else having this problem?
Sounds like you have a connection problem between your house and the Glitch servers. It will probably clear itself up in a fairly short while. If it doesn't, you'll probably want to check with your ISP to see why you can't stay connected to Glitch.
Actually they said they were testing rolling restarts this morning; many folks had this. I'm sure all will settle down soon, but if not, please come ask in Live Help channel! :)
