Question split topic doesn't move subscriptions

When I split a topic with say 10 messages from 10 different users, subscriptions made to that topic, are not moved to the new one.
Is it a known bug?

A topic is defined by the first post in a thread. Therefore, if someone subscribes to a topic then the subscriptions follow the thread to wherever the first post is moved. If you split a topic in the somewhere in the middle of a topic, or 10 different ways, then the subscriptions only work for the topic/thread that's defined by the original "first post". Did that make sense?

It's not a known "bug" as such. That's just how topic subscriptions work.

If you already are a subscriber on topic A, and the topic A is split into A and B, then you should be automatically subscribed to topic B as well. I think this is obvious and i think it should be the default behavior.
If you split a topic in the middle and therefore you create a new one, the subscriptions should be moved, at least for the people who participated in the discussion after the post that is now a new thread.

Sorry, that's not how it works. That may be how you think it works but that's not how it works.

If you have a topic A and you split it into A - that contains the original first post - and B, then only the subscriptions for the new category A will survive.

On the other hand, if you have topics A, B, C, D, E ... etc., and people have subscribed to each of them, individually, and you merge them all into a new category (X, say) then some or all the subscriptions may survive the merge.

Splitting and merging is tricky as far as subscriptions are concerned. I haven't spent enough time testing all there is to know about them. Perhaps someone else knows more than I do.

When you "subscribe" you actually tag a specific message record, one that defines the start of a topic. You can check this for yourself if you look at the jos_kunena_subscriptions table in the database.

That's the way I think it should work. I know that it doesn't work like this, that's the reason I reported this on the first place...I checked the db before posting and I saw how it is functioning.
Anyway, thanks for your time!
I guess that I have to move/copy subscriptions manually every time that I split a topic
