LaserCucumber reported a server crash resulting when MyWorlds portal handling was disabled. This was tracked down to be a bug in BKCommonLib that triggered an infinite portal teleportation loop, which Ive fixed in the new -v3 dev build. This updated version includes a workaround to fix the same bug that will work with the released BKCommonLib version.
Also fixed: it no longer shows a World join message twice when using a portal for teleportation.
This build supports all Minecraft versions 1.8.8, 1.9, 1.9.2, 1.9.4, 1.10.2, 1.11.2 and 1.12.
