Subscribed threads don't show up under the activity list unless the parent forum is subscribed to as well. Look at thread 1890129 against my account for a testcase. Send me a PM if you need me to retest.

For example, this thread (which I posted to, and therefore am subscribed to) does not appear on my list (Another data point)

marty - good catch. I have the programmer checking into this bug

Do you guys have a fix I can test?

I'm going to test this one. I'll impersonate you to test again. If I can duplicate (which we could not do yet) we can find the bug.

I can see the bug so we should be able to nail it

It works when I enter from "All Forums"
Still broken when I enter through "My Forums"

yup. we should have it fixed this week

new code is in place. please test and report back to confirm if fixed

Fixed on my end. Looks good. Thanks.
