Subscribed threads constantly unsubscribing?

[Charles8088]

I have no idea how to subscribe. I just come to the site and pick which thread I wish to read and respond to.

Are you just going through Tapatalk or the site directly?

Not Tapatalk... through the site directly, on my computer. When in a particular thread, such as this one, at the top under THREAD TOOLS you can subscribe to the thread. This allows me to quickly look at my subscribed threads from the User Panel and see if there are any updates. But, for some reason, some threads constantly unsubscribe for no rhyme or reason. Not a huge big deal, just a little annoying.
