when you log off a server on a horse, the horse duplicates (and so do the items if you are on a donkey or mule) and i keep getting server issues on my server. my server is a lenovo thinkcentre intel core 2duo - 2.66 Ghz with 6 gigs of ram. 2013-05-16 15:36:44 [WARNING] Can't keep up! Did the system time change, or is the server overloaded? [SEVERE] Reached end of stream I keep getting these errors, even when nobody is on.
