MC 1.16.4 - Forge 35.1.4 - FP Futurepack-1.16.4-31.1.8176

I have not done a great deal of exploring but the closest two dungeons to my bed have some new features which I long to master. However I wonder if this current behavior is not better described as being unintended. So I have questions that might be considered bugs, I'll let you decide.

1. There are multiple force field "gates" sometimes before Gate 1 and sometimes after Gate 1 which prevent passage through the dungeon. I do not know if later Keys are needed as I cannot get to Gate 2 in order to obtain Gate 2 blueprint. I am wondering if the new Disc study is related but I am just wondering as I have only Researched Mincra and the result of that is 'story.nav.nincra' not found, report this to the mod author -- which I have not yet done.
2. There are levers on some walls which open doors in hallways that are completely inaccessible. Perhaps I should have started with that. There are passage ways in the dungeon which are not attached to the hallways connected to the entrance portal. Also some of these hallways have doors which are opened and shut from hallways which are accessible. I only know this because of spectator mode.
3. There are doors in the main passage ways which are only openable by using spectator mode and phasing through the wall to get the inaccessible hallway and changing the lever.
4. I love the water features and the two story rooms which might be the solution for item 3 but I have no grapling as i have caught not slimes (my problem but I doubt grapling was an intended requirement for moving about the Dungeon as before when ladders would not stick to Quantianium blocks and grapling was required to travel, that was considered a defect.
5. I think I like the introduction of magnetic pulse blocks and the rail system but I can't tell if it is a "fun thing to do in the dungeon" or if it is somehow part of how to travel. Perhaps this is also part of the fix for item 3. Except I think I had to spectator-survival just to enter this room.

So my question is, is any of this intended? If not, I am willing to make defect reports for any or all of it, and I can still do the rest of the research and adventuring and searching for Dungeons that seem less self-conflicted.

New version and dungeon's have been restored!

I made a new world with 1.16.5 and 36.1 and Futurepack-1.16.4-31.1.8176, and found a dungeon but using creative and spectator I was only able to reach the 3rd gate but from there I could not reach the end.
