I've come to notice this bug when i was reading a thread and it says:
Planet Setup:
- Can not setup planetary contruction asteroid if foreign space station or foreign fleets in system
- setup costs: about 10 days of mining, lots of stone and carbon.
If planet:
- Can not setup enemy system fleets
- Can not setup enemy space station / structures
I've tested the statement by building a station in the test server that has a planet without a station but this is what I got
Now this is were the bug comes:
When you try to deploy a warp bubbled station, you can successfully install it
The station is supposed to be undeployable when there is a foreign planet in the system...
