Please have a look at the top post of this threat. I uploaded mercator verison 0.9.1 preventing entities of tjhe same owner placed twice at exactly the same position. It also enforces the game rules  Putting a building on top of a tree or rock is refused. An object placed on top of an actor (citizien or other) creates a warning (the game seems to allow that) Objects off the map: refused. Mercator now also support defining screenshots taken in Atlas or putting its own simplified map layout as in post-atlas.

Yes a herd of elephants getting stuck on a narrow path is somewhat acceptable but in the video the bouncing was way too awful.  The reason why I would give this new "solid" propriety to only melee elephants amongst all land units, is that it's one of the costliest units. And "solids" having inelastic strong pushs, it will always make a large group of such "solids" always a bit tricky. But it doesn't mean that it should look as sh!t as in your video neither.  I found a few bugs, improved some of the physics, and made couple tweaks that try to address that. Ideally we can still have "solids" do the minimum of overlapping. Tell me if you manage to test and still reproduce the weird bouncing!

I made a post asking for references. What do you mean by the original? I used several references. I created it from many interpretations of Helios. I used one I saw as a base. It can be easily changed.

Chosen Athenian sounds a bit strange tho, maybe “Chosen of Athena”? Same meaning, but reorganized name.

A new release is planned soon, but till then I hope this holds y'all over: https://www.moddb.com/mods/hyrule-conquest-revival/news/lots-of-new-stuff-coming-soon
