Possible errors and Pach question

[Warmskin]

OK, first of all, I bought this retail version DVD at a store and it says it is version 1.6b7. I have noticed no problems so far (level 7) except I don't see any portals on any maps. No big deal. Is this new patch (1.6.5) for me (English, retail vers.)?
Also, I have noticed a few odd things happening...
When I use 'Magic Shackles' on Skeleton Archers there seems to be no effect.They can still use both their talents and abilities (they shoot me and use poison and black arrows).
And 'Devilfish' are moving twice in one turn. They move, someone else moves and the same exact troop of devilfish move again. No, this is not an end of turn - begin new turn issue.
Any clues w/b greatly appreciated. Thanks.
