shs is not displayed on node edit form when previously selected term is deleted

hmm, everything works when clearing cache, but still it is a bug.

My install is semi-clean install, with not much modules. What I did:
1. Created vocabulary with terms, most of them single hierarchy, some had 1 level of children
2. Created node type with required shs field, with the requirement to select the last child.
3. Created node content, selecting 1st level shs term (it was also the last level)
4. Deleted that term in Taxonomy manager.
5. Opened node edit form - cannot see widget at all. Refreshed page - no change.
6. Cleared caches - everything works.

Server is Wampserver Apache + php 5.3 on locanhost win7 machine, not much extra config made

Ok, I have repeated the same steps and in "5" step I still could see that already deleted term, but when I selected it and pressed save:

    Notice: Undefined index: 22 in taxonomy_field_validate() (line 1519 of C:\wamp\www\site1\modules\taxonomy\taxonomy.module).
    Notice: Trying to get property of non-object in taxonomy_field_validate() (line 1519 of C:\wamp\www\site1\modules\taxonomy\taxonomy.module).
    Modelis: illegal value.

and cannot see the widget.

After edit page refresh with f5 or ctrl+f5 I still can see that deleted term and if I select it - the same error message appears (and no widget).

I am using Entity cache and Javascript callback handler modules, but with them disabled no change.

btw, I cannot see the widget from the beginning of edit if the term which was deleted was the first in vocabulary

I am getting the same bug without Entity Cache also. Will wait for next dev t.y.
