So, the primary issue is some quite creatively 'broken' animated objects, which are used as grounds- Large numbers of similar objects:

[object]
states=..\Tree\field2.b3d
rotateXfunction=sin[time/3]/2
position=0,-2,29

I think the author was attempting to create a swaying grass effect with this.

It will load (eventually), but it's got all sorts of issues, and I'm not sure this is easily fixable.

The PR above gets the loading time back to something more sensible, but I want to do a considerable amount of testing before merging it into the main public branch, as I don't want to break something else.

(Note: I seem to be missing various of the objects with just your link, but this doesn't really matter at this point)

FWIW, I note that this must have been built with an relatively early (pre GL3 I'd say) build from this project, as Michelle's 1.4.3 doesn't load it :)

Fixed in the current daily build, although the fix for the minute is controlled by a hacks option as I'm not certain it won't break other stuff.

(n.b. your download is missing a bunch of the objects, and so things appear somewhat broken, and I haven't really tested the route itself)
