First Issue, my Dup got stuck grasping to an Algae Deoxydizer somehow. Then I deleted it and he was still stuck in midair and wouldn't move! I ended up being able to get him down by building a block under him and deleting it (it bumped him up a tile) before he starved.
Second Issue, Just a graphical bug, went down the entire side of the map and through different zones.
Third issue I mentioned before, I ended up having to move the filtration system to a different area for them to add sand.
Unsure of how to recreate these glitches, and since the new patch is coming out i'll have to just play until I see them again to figure it out.
