I don't know if mods can ever be perfect... I think you'll always find something – or more ideas will come along to expand the content even further.
But even if you don't think they're perfect, I see them as a larger quest expansion project that has taken a lot of effort, work, and time to create, and that offers a multitude of new possibilities and good motivation to play the game.  

Great, the problem with the spear has not only been fixed, but it has also been replaced with a better spear. Thank you for looking into it so quickly. 

Yes, I also suspected that the hatch was random – especially since the path is only opened through dialogue with Bently. But I have another suspicion, which I need to check again first.
Strangely enough, it happened again today that the hatch was already open before I accepted the quest, but it doesn't bother me—I ignore it and, as it should be, accept the quest before going down to the basement.
