I found a whole bunch yesterday:
- Outbreak Event: The Malevolent chioce only effects the planet, not the whole civ (as it should)
- If you have a commander fleet on the same tile as a normal fleet and click on "manage", then the logistics bonus isnt applied to the commander fleet in the "manage" screen
- "Caverns" tile bonus still gives +3 Resistence
- I got a stuck turn when I got a trade offer as the last thing to resolve before the end of the turn (had to save and reload to see, that there was a trade offer)
- The Economic Focus "Trade Economy" says, it would increase Trade Value, but it instead increases Planetary (Gross) Income
- The Stellar Forge gives separate adjacency boni to Social Construction and Ship Construction, instead of giving boni to All Construction. But this way it doesnt apply to "All Construction" buildings, which should be changed.
- Spies can level up on planets and there even is the technology for them to get an additional level, but I couldnt find anything that changed, when they get extra levels. Either it doesnt work (needs to be fixed) or the player needs to be better informed, which advantages higher leveled Spies get.
- Durantium Cloud colonizing event: Benevolent Choice gives +1 Raw Prod, the text says it would give +5
- There is an event (sth about +100% Ship Range), where the Benevolent choice also gives the player +9 Diplomacy. This seems to be overpowered. [I couldnt find the event in the game files, maybe someone can give me a hint, where to find it 
]
- The "Xandar Homeworld" United Planets Resolition seems to have no effect. (Maybe only in my game, where there are no minor factions)
- United Planets Headquarters (+50% Influence for the selected race) also doesnt work
- The "Beyond Mortality" Ship Components arent available in the Designer after researching them.
- The Planetary Specialization "Soil Enhancement" doesnt give any food.
