Necromancer minions vanishing from party

[Tanit]

Character: Necromancer
Skill for case #1: Assemble mastery level 5 - Eternal Bone Giant + its Re-Assemble skill or Sacrifice
Skill for case #2: Create Minions + Re-Assemble + Fearscape

2 bugs:

Case#1: The Eternal Bone Giant, created via the Necromancer Skill Re-Assemble vanishes from the party after it re-surrects itself or after it is sacrificed in favor of a Bone Shield with the skill sacrifice. I'ts probably not intended... although it still keeps following the player, the downsides are that you can not sacrifice that once re-surrected Eternal Bone Giant and it does not follow you into the next zone (the up-side is that you get an additional follower 5+1). I just wanted to bring this to attention, in case it's not working as intended, correct me if I'm wrong if it is. I didn't find anything in the skill descriptions or forum search regarding this matter.

Case#2: I had 3 minions with my necromancer, entered the fearscape, created a Bone Giant out of 3 minions that were not inside the fearscape. After I got back into the real world the 3 minions where still alive, but not in my party. I believe it would be better if they were dead instead, because I sacrificed them after all.

It's easy to make a lot of bone giants with hidden resources, create minions, assemble, sacrifice combo. Then if too many of them are affected by AoE effects the game is going to crash.
