You modified "slides" twice

[BenjaminHorn]

After fresh ember install:

{{#twbs-carousel indicators?=true as |carousel|}}
  {{#carousel.slide as |slide|}}
    {{slide.img src="https://dummyimage.com/1600x900/f7d3a0/333.jpg&text=Slide+With+Indicators+1" alt="A slide image."}}
  {{/carousel.slide}}
  {{#carousel.slide classNames="active" as |slide|}}
    {{slide.img src="https://dummyimage.com/1600x900/f7d3a0/333.jpg&text=Slide+With+Indicators+3" alt="A slide image."}}
  {{/carousel.slide}}
  {{#carousel.slide as |slide|}}
    {{slide.img src="https://dummyimage.com/1600x900/f7d3a0/333.jpg&text=Slide+With+Indicators+5" alt="A slide image."}}
  {{/carousel.slide}}
{{/twbs-carousel}}

Error: Assertion Failed: You modified "slides" twice on <x@component:twbs-carousel::ember264> in a single render. It was rendered in "component:twbs-carousel" and modified in "component:twbs-carousel/slide". This was unreliable and slow in Ember 1.x and is no longer supported. See emberjs/ember.js#13948 for more details.

Oh my goodness, sorry @BenjaminHorn; I just saw this today...not sure how this slipped through the cracks. I'll take a look some time today.
