[1.7] [BETA] Defense Fighters have problems

I have encountered several problems with the interceptor fighters in the 1.7 beta.

With interceptor fighters I mean the fighters starbases and planets get from the Paranoid Ability.

- If a planet with interceptor fighters is attacked the planet and its map icon get invisible. The outcome of the battle is irrelevant.

- Interceptor fighters are invisible in the combat viewer and their stats are bugged. They also seem to be unable to attack. They can be attacked and destroyed however.

- Interceptor fighters sometimes appear in the shiplist in the diplomatic screen. When I tried to trade them the game crashed.

I don't know if it is related to interceptor fighters but a pirateship tried to attack a station with 2 defending interceptor fighters. This crashed the game. after a reload the battle was carried out normally.

Is anyone else experiencing problems with interceptor fighters?

Edit:

Hovering over an interceptor fighter in the pre battle view to see the stats seems to crash the game.
