XenForo bug

J just turned on my computer after it being off since Saturday. When I logged into XenForo in Firefox, the first thread displayed had skipped an unknown number posts. I found them, but I expected to read them automatically...

You are the only XenForo customer, the rest of us are not (unless we subscribe unrelated XenForo forums), As such, yours (or your agents) is the only voice XenForo listens to. How do I know I received the whole thread?
