Server controlled tile updates... not updating

[DustyPorViva]

It seems server-controlled tile updates(redrawing bushes, pots and such) are actually not being tracked by the serverside, thus making serverside tile checks unreliable.

I placed a putnpc2 at the position of a bush. On the serverside, I check if there is an actual bush at the placement, if not, destroy, if so, remove the bush and replace the tiles with the cut bush tiles. I wait for the bush to regrow and place the NPC again. This time, however, it returns that the tiles at the placement are still the tiles of a cut bush rather than grown... and it stayed like this until I updated the level.

This makes it kind of hard to deal with this sort of tile updates on the serverside when after the first use it will no longer work.
