I love this mod but at the same time I have been very disappointed.
The new buildings seem to me to be incredibly well made, even much better than the current ones in the official game, it shows that the people who created them have made an effort, but...
God, quests in these buildings are like a pain in the ass. The official buildings (vanilla) are created in such a way that you don't need to break any blocks to complete the quest, and that seems incredible to me, because otherwise, you would spend an immense amount of time to find where the zombies or the package are, which is what happened to me with a custom building of this mod. Most (or all) of the buildings in this mod can NOT be completed without breaking doors and / or blocks. I just did a simple Tier 3 mission to clean up zombies and it took me a whole day just because the building didn't tell me where to go and everything was closed. Closed doors, places closed with wood, etc. I had to break a lot of blocks and doors to find the zombies.
Just the buildings themselves are incredibly elaborate, but every time there is a quest in those buildings I will have to reject it, because it isn't that it's difficult, it's that it takes a long time because there is no "established path".
I don't know if there is any way to solve this, but if there is I would love to know, I have fallen in love with the buildings in this mod and when I saw that there were also quests in these buildings I was very excited, until I saw this problem...
