community tags removes forum association if post tagged after create (missing posts)

using advanced forums I don't know if the same problems exists without it it

do the following after installing module and associating vocabulary with forum type

Say you have two forums

lego discussion
widget discussion

create post say in the widget discussion forum

*after* you create post go back and tag your post
this will remove its association with the widget discussion forum and it will no longer show.

the problem seems to be rooted in the modification to the term_node table after you tag it.

The forum association record is getting deleted from there when I think it should be left intact adding only the new record for the tag just created.
