MorphReplace with more than 2 Icons

Hey, 

I've got it working with two icons, but as soon as I add more, it stops working
I have an array of jsx elements and a counter in the state, hoping to use it as a loading indicator:

`
<MorphReplace width={size} height={size}>
     { icons[this.state.counter % icons.length] }
</MorphReplace>
`

Any help with this? 
thanks in advance
