Vue.js weird behavior of router after refreshing page - vue.js

Question

I have a problem with dynamic routes in my vue.js application. When i enter page from a routerLink click everything works as it should. But when i refresh that page or i enter there from normal href the page acts weird. It looks then like it's not loading static assets like styles which were reset in public/style.css. Also component lifecycle methods are not firing up (created(), mounted() etc.).
Reproduction here:
1. Enter https://blooming-dusk-66903.herokuapp.com/profiles
2. Enter on one of profiles
3. Refresh when on https://blooming-dusk-66903.herokuapp.com/profiles/*******
here is my router file
Vue.use(Router);
export default new Router({
mode: "history",
routes: [
{
path: "/landing",
name: "Landing",
component: Landing
},
{
path: "/register",
name: "RegisterForm",
component: RegisterForm
},
{
path: "/",
name: "Dashboard",
component: Dashboard
},
{
path: "/profile",
name: "UserProfile",
component: UserProfile
},
{
path: "/profile/:id",
name: "Profile",
component: Profile
},
{
path: "/edit-profile",
name: "EditProfile",
component: EditProfile
},
{
path: "/friends",
name: "Friends",
component: Friends
},
{
path: "/profiles",
name: "Profiles",
component: Profiles
},
{
path: "/friend-requests",
name: "FriendRequests",
component: FriendRequests
},
{
path: "/post/:id",
name: "Post",
component: Post
},
{
path: "/chat/:handle",
name: "ChatWith",
component: ChatWith
}
]
});
