When an ogre or troll loses their tackle zones from Bonehead/Really Stupid, they still seem to be able to assist in blocks according to the block wording. But they can't cancel out other people's assists:
This just seems to be the opposite to what should be the case, logically (if logic has any part to play in this matterIn order to make an assist, the player:
1. Must be adjacent to the enemy player
involved in the block, and...
2. Must not be in the tackle zone of any other
player from the opposing team.

Is this a screw up in the blocking wording, or is this how it's supposed to be played?
