1. In Research Complete screen thwe rotating frame of the weapons technology accompanied information that I just researched xenofarming.

2. United Planets Council screen appeared without a pop-up warning one turn before.

3. After I was awarded a habitable planet and found it I discovered that none of 8 useable tiles were used. No starbase, no starport - nothing. Yet Planet was building collony ship and after 15 turns I was able to lounch it, still without building starport or anything else at that planet. Once I lounchwed my colony ship, the planet conntinued to build next colony ship, this time indicating that it will need 32 weeks for that.

4. After about 45 minutes or one hour of playing without any problems the game froze and Windows task manager indicated that the game was using 98-99% of CPU resources and 358 472 KB of my memory.

Also, although I am not sure that this is a bug,I started the game surounded with 3 minor races that again started shooting out series of colony ships (4 to 5) that were unconcerned with range limits (at list ones that very much cocerned me), Later in the game I found that their choice of colonized planets was rather funny. They colonized bunch of 6 or 7 quality planets while ignoring 11 or even 12 quality planets in their own home star star system. Also their minor races are now able to build star bases. That was not the case (if I remember well0 in GalCivI.
And home planets of all (in my case at least 3) minor races seem to be quality 15.
