Hey! I'm glad you like Shades so much. While it's not a perfect mod, I wanted to go for this old type of mods that includes both quests, expands some existing stuff, include now monsters, items, and other things. Like a general expansions of a whole game. 

In regard to bugs you experienced: I will definitely need to check that spear! It sounds like it has an "unmovable" property on. As for the hatch: I think it may be some coincidence, as for the hatch to open a very specific variable mist be picked, there are no chapter checks or anything that I can think of that could interact between those two mods. Let's just hope it was just some hiccups of the engine and you won't experience such problem ever again  

Cheers!
