There are still some unfixed issues (alpha12-2): the EH is stuck after a combat and no expo result message is generated.

Three expo fleets were started a few seconds apart:

Expedition Result [1:10:16] 20.02.2015 14:23:10
From: Fleet Command
The new and daring commander successfully traveled through an unstable wormhole to shorten the flight back! However, the expedition itself didn`t bring anything new.

Entry from the communications officers logbook: It feels great to be the first ones traveling through an unexplored sector.

From: Fleet Command
Besides some quaint, small pets from a unknown marsh planet, this expedition brings nothing thrilling back from the trip.

Addendum: Maybe it is possible to let [fixed]-threads open? I don't see any spamming here and sometimes it would be useful.

Today:

1st Expo:

Expedition Result [1:30:16] 24.02.2015 13:20:50
From: Fleet Command
Your expedition fleet made contact with a friendly alien race. They announced that they would send a representative with goods to trade to your worlds.

2nd Expo:

Expedition Result [1:30:16] 24.02.2015 13:21:02
From: Fleet Command
On an isolated planetoid we found some easily accessible resources fields and harvested some successfully.

Crystal 11.640 have been captured.

3rd Expo:

Combat Report [1:30:16] 24.02.2015 13:21:12
From: Fleet Command

Attacker: (Aliens): 0
Loot:0
Debris field (newly created): 0

Defender: (kfg): 101.000

0
Moon Chance: 0 %

No lag this time, but no Expedition Result message either. No drunk pirates, no alien invasion fleets, ... nothing at all.

PS: Maybe the lag comes only after the generation of the Combat Report and would then affect the following Expo Report message? I will look out for that.

... and found something:

Expedition Result [1:30:16] 23.02.2015 23:27:12

Your expedition discovered a small asteroid from which some resources could be harvested.
