Summary0007981: Grasstrample has no effect
DescriptionExactly what it says. The GRASSTRAMPLE tag is now completely non-functional, or so it seems.
Steps To ReproduceMod your game so your dwarves have GRASSTRAMPLE:50, which before would've instantly crushed the grass into nothingness. Watch as they spring with a light step over the terrain and even the most densest of grass patches suffer no more than they would the step of a ghost.
Additional InformationProbably has something to do with the movement changes.

Additional info: this was always one of the things that I really liked, which is probably why I apparently noticed it was broken before anyone else... I'm just surprised it took a whole month for someone to notice.

On further investigation, it appears that GRASSTRAMPLE still functions, but very, very differently than it used to, and at a much lower rate. It takes nearly a year of ingame time with dwarves at [GRASSTRAMPLE:50] in order to see much of an effect, and it still appears sporadic and random (i.e. trampled grass interrupted at random points by patches of dense, untouched grass).

Is it possible that GRASSTRAMPLE is only reducing one of the 100 "units" of grass at a time?

I can't speak for adventure mode (is it even in there?) but I've seen lots of grass trampling in my multiple forts within 40.08... I often have large herds of puppies/dogs, poults/turkeys, etc. sitting around a single 21x21 movement area.

It could be related to your second note, as they generally sit in the pen/pasture for 6 months to a year (2 years for the 50+ poults and occasionally a month before slaughter) - but I don't put anything that grazes in that area (grazing also appears to be working fine for me)...

dree12: that's almost definitely what's happening.

I analyzed GRASSTRAMPLE back in version 0.31.19 when dense grass was added, and each "trample" depletes 10 units of grass in the tile (of a possible 100); it stands to reason that it still works that way in the latest version.

An interesting addition to this:

Grasstrample has little effect on grass, but the effect on cave moss is exactly the same as it was before.

I've done a little experimentation; this still exists in 42.01.
