Embark, please adjust the interrupt 10 times weekly.

Now to be clear here, I am at 9/10 done. I "got mine" but for the sake of those who haven't - at the very LEAST make it so your teammate interrupts count for you as well. This is actually a very good lesson to be taken from Fortnite, the real annoying challenges or ones that you are actively competing against your teammates for, have co-op progress.
