None of the local resources around us are contested, nobody cares about them anymore and nobody contested them before, actually. All the people I've talked to are annoyed by this change and (to our benefit) some of them stopped collecting local resources 'cause they don't feel like wasting so much time. One of my routes through caves contains 5-6 local resources and the time wasted is noticable. On my sea routes I often hit more than that.
And I'm pretty sure it shouldn't reset the timer when you run out of inv space. Reproduction: run out of inventory space while collecting heartwood leaves, make more space, try to harvest leaves again, get another 2 minute timer.
You can still leave this on ice spires or salt basins(?) where the change might still matter... did it ever matter? Have you actually checked?
Please remove the timer, it's super annoying.
