I'm seeing in my build that this section is getting jumbled up. I'm still trying to figure out why though:

var __WEBPACK_IMPORTED_MODULE_0__angular_core__ = __webpack_require__(1),
    __WEBPACK_IMPORTED_MODULE_1_rxjs_ReplaySubject__ = (__webpack_require__.n(__WEBPACK_IMPORTED_MODULE_0__angular_core__), __webpack_require__(19)),
    __WEBPACK_IMPORTED_MODULE_2__angular_common__ = (__webpack_require__.n(__WEBPACK_IMPORTED_MODULE_1_rxjs_ReplaySubject__), __webpack_require__(3)),
    __WEBPACK_IMPORTED_MODULE_3__angular_router__ = (__webpack_require__.n(__WEBPACK_IMPORTED_MODULE_2__angular_common__), __webpack_require__(5)),
    __WEBPACK_IMPORTED_MODULE_4_rxjs_add_operator_filter__ = (__webpack_require__.n(__WEBPACK_IMPORTED_MODULE_3__angular_router__), __webpack_require__(20));
__webpack_require__.n(__WEBPACK_IMPORTED_MODULE_4_rxjs_add_operator_filter__);
__webpack_require__.d(__webpack_exports__, "a", function() {
    return Angulartics2
});

edit: this isn't the problem.

I was using systemjs-builder 0.16.9 and downgraded to 0.15.34 and it fixed the problem. It might have something to do with this open issue: https://github.com/systemjs/systemjs/issues/1587

I can confirm this. There seems to be real issues when using SystemJS 0.20.x . I have pushed a very minimal seed-project with angulartics here:

https://github.com/ZuSe/angular2-seed/tree/test/angulartics2

But i only run into the issue when compiling aot.

I think there was some issues with older version of rxjs and older versions of systemjs. Let me know if this can be closed.
