I could use some clarification on a few potential bugs I've encountered. So after grinding a bit i decided to try this lost sector again at power level 1237. I know this is still to low but i had to use different weapons then i normally use otherwise I'd be at 1240. So while doing the lost sector I've seen that a Champion Servitor's immunity granted to other fallen enemies reaches extremely far and goes trough solid objects. Now correct me if I'm wrong but i don't think this immunity beam the Servitor gives should be able to pass trough solid objects. This effectively made enemies unable to be killed because the Servitor itself decided to constantly hide behind a wave of enemies. At multiple times i had to wait and hope this immunity would deactivate on fallen enemies so i could kill them quickly. Secondly i got killed because exploding Shanks were literally passing trough solid objects. I was standing on one of the small building within the lost sector and out of nowhere these Shanks came up trough the roof and exploded in my face before i could escape the blast radius. Now unless these Shanks have new techniques I've never heard about i don't think they should be able to pass trough solid objects. Also on a side note. What I'm about to say isn't a bug but i do feel like its relevant. I've noticed that multiple heavy weapons are of little use against Champions. To me Sword feels like the only relevant weapon to use against them. But this might just be based on my own experience.
