Strange compiling bug

When you change a interface the TSLinter and the Angular CLI are not throwing errors anymore? It happens with different things too. When i run ng serve again for example it works again or it throws errors. But while changing files it seems to remember old stuff..

When you have a file with interfaces and have imported them somewhere else, and then start the project by ng serve it works correctly.
But when already running and reference to a exported interface it stops working.

Versions.

CLI RC2
Node 7.8
YARN/NPM

Repro steps.

Make a interface, couple it to a function

The log given by the failure.

Desired functionality.

Working again, so it needs to throw and error.

Mention any other details that might be useful.

Another simple example when it happens:

I had:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { CoreModule } from './core/core.module';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    AppRoutingModule,
    CoreModule.forRoot(),
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

I changed it to:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { CoreModule } from './core/core.module';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    ReactiveFormsModule,
    AppRoutingModule,
    CoreModule.forRoot(),
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Then I save it and cli is auto seeing the changes and gives this error...
Then im getting the error ERROR in /repos/vreugd-online/src/app/app.module.ts (18,5): Cannot find name 'ReactiveFormsModule'.)?

When stop the cli and run ng serve again then it works again.
