something wrong with exploation 1.3.0.4

[Xmudder]

My game under 1.3.0.4 has had some odd things happen:

1) Nebulas with points of interest are being ignored by my Medium Exploration ships with T3 components (Ion Shield, Ion Sheath Armor, Corvidian Shields v2, Gerax Hypedrive v2). There are still a few to the north of my empire towards the Human one in this save. Works fine if I manually send fleets there.

2) The Atuuk empire never fixed a spaceport in their home system (EP854 spaceport in this save)

3) The Quaemo never explored their home system, so I got the "earthquake on homeworld that boosts reseach" event when I explored their home system.

4) The Quaemo are restricted to their home system, which is inside the "Sol Morass" gravitic storm.

5) It took forever (T3) before my exploration ships penetrated the regular nebula to my north, limiting exploration in a region no one was in, due to the Quaemo Homeworld being way too close to Sol.

6) compressed save (7z) is 13meg, too large to attach.
