Part Disappeared
 

Hi,
I am on an FTC team, so I hope this is still the right place.

I downloaded the kit of parts a week or two ago, and all was fine. Then yesterday, I received an email from a mentor on our team telling me that one of the parts was no longer in his Kit of Parts that he just downloaded. This part was the 416mm channel.

Can someone tell me if this is still a valid part to use, or what exactly happened to this part?

Thanks!
