Resolving MCPC-Plus and Spigot crashes whenever a second player joins

❗️
MCPC-Plus is no longer available for download. Links on this page won't work.

Starting on March 26, 2013, servers running Spigot or MCPC-Plus for Minecraft 1.6.4 or 1.7 may crash every time a second player joins. The cause is a time-related bug with the server code. To resolve the crashes, update the server JAR to the latest build.
