NPC behaves as it's parent on packaged game

NPC behaves as it’s parent on packaged game:
Some values are take form parent’s default (the values that are changes on level are ok, but those changed in npc blueprint are restored to parent state).
Can’t use their AI Controller (same - they’re tring to use parent one).
Some other problem with these npcs (game dosn’t work as in editor).

This is a project converted from 4.7 to 4.8. On 4.7 making a package made no animations (but logic was ok), on 4.8 animations are ok but with broken NPC logic.

Can I do something with this? On editor there are NO PROBLEMS.

I tried different configurations, and looked for workaround for over 6 hours

Any ideas?
