2. Players who use Minecraft's vanilla "wide-char" English font(instead of Unicode's "thin-char" style) will be unable to type "[Missile Interceptor]" in one line, making missile interceptors no sense for them. So the set-up sign of missile interceptors has been changed. Go to https://doc.snnyyp.cn/icbmBukkit/missileInterceptor/ to learn more about the new way of setting up a missile interceptor
