[BUG] Delete post in test board lowers post count

[۞]

Yes, me again

If i post in the test board, My post count does not go up. But if i delete the post I just made it goes down.  In theory, It should be possible to get a negative post count like that

you can't get a negative post count with the new structure, but that shouldn't be.

Fixed.
