XF 1.3 The requested thread could not be found

[imthebest]

Today I discovered something very strange.

I just started my forum about 3 weeks ago and have not yet physically removed any thread however I'm now trying to access some threads by URL:

threads/whatever.250 (loads a thread fine)
threads/whatever.265 (loads a thread fine)
threads/whatever.280 (I get error "The requested thread could not be found")

And there are some other thread IDs that are returning this error message which I don't understand how it could be happening if I haven't physically removed any thread and currently I have no moderators, I'm doing the job alone.

Btw my forum statistics says "Threads: 314" however the thread ID of the last thread posted on my forum is 389 and the last before last thread posted has thread ID 386 and when I try to manually access threads 387 and 388 via URL I get "The requested thread could not be found".

What could be happening? Could it be due to the fact that within the last few days I moved some threads leaving a redirection notice that expires in 1 day?

I'm really worried, I don't want to experience data corruption on my database, please help!

Thanks,

P.S.: I don't know if it helps but recently @Waindigo's add-on Discussion Count started to fail in the counting for example a new member registered today only has 3 threads posted however the add-on is reporting 6 threads to be owned by the member but there are only 3! The same is happening for other members for example there is a member with 85 threads however the add-on says 90 threads.

This is likely the reason.

Thanks for the info Andy! Anyone can confirm this please?

Redirections will do it, but thread IDs can be used for any reason. The short version is that they're allocated internally and they're just a unique identifier, nothing more.
