Trouble accessing populated $node using node_load($nid) from theme override of taxonomy_router/tr-node-item.tpl.php

Context: I am using Taxonomy TreeMenu with Taxonomy Router because Taxonomu Menu is failing with multiple parents and "display descendants".

#498226: Primary Links menu completely mangled, and stayed mangled after switching off module !

#498182: Support for a term with multiple parents

This gives descendants also, however the display from taxonomy_router/tr-node-item.tpl.php (and taxonomy_router/page-branch-list.tpl.php) is not what I want, I'd like to make it look like my regular highly customised teasers.

However the teaser code from my custom node-MYTYPE.tpl.php requires a populated $node

The $nid is provided by taxonomy_router/tr-node-item.tpl.php, so in my override I try to get at $node using:

$node = node_load($nid)

OR

Then I simply include my own .tpl.php (as used for front page teasers and custom type body).

It works only partially, as the $node does not seem to be fully populated (contrary to the docs on node_load). The current result can be seen here:

Compare with the front page teasers:

The only thing that seems to be in $node is the title, otherwise it's empty.

I also tried to use the cache reset, it did not seem to have any effect:

Q: How can I ensure the $node obtained from the $nid is properly populated ?
