Can confirm and I am also interested in why it's behaving like this. As it is right now it seems to completely ignore the costmatrix for adjacent tiles.

@Revrick, Dissi: a link also returns ERR_TIRED while still cooling down.

Regarding your billing idea: I don't think that's fair, unless the developers also have to pay less rent and spend less money on groceries when the tick time goes up. I don't really think I'm paying for server utilization. I'm paying for them to keep up their work. That's about it.

But yeah, 5s per tick and I'd need to get back to real life...
