After using the Entrenchment Beta for over a dozen single player games, I have noticed some repetitive bugs. If these have been covered, please excuse the repitition, and if these are not bugs but settings issues, please advise.
1. Dissapearing ships/structures w/in a grav well.
During some games (Typically 2-4 AI, 20-50 planets), most object icons dissapear unless zoomed in fairly tight (like 1/4 of the planet more than fills the screen). It is almost impossible to manage a medium to large battle when you cannot see where your opponents structures and ships are (nor can you highlight your own directly). I Initially thought this only occured when the well was saturated with mines, but that is not the case, though the sheer volume of mines in the whole scenario might be the culprit. (This only occurs later in the game when most of the planets have been initially occupied.) Gamebreaker.
2. Vasari and TEC colony ships go on alone when grouping Cap ships and sending them to another planet. (I have not tried Advent.)
Say you have a Vasari Carrier, Colony ship, and planet buster in a grav well, and you highlight all 3, right click the 3 arrow team up button, then right click the next planet over. They should all line up, wait for each other, then go together, right? What has been happening is the Colony ship sets the course, but the other cap ships just sit there. So if you send the orders then move on to another situation, you might come back to find your colony ship being shredded, and your other ships lounging in the original grav well. This is all the more annoying as there is no way to beat it--that is to say, if this happens, the only thing you can do is send them seperately, just try to time it right. The colony ship always gets the blue line right, the others don't. Major annoyance.
3. Dissapearing planet images from medium down to grav well zoom.
Interestingly, this also breaks the smart zoom feature making it almost impossible to zoom in on the juncture of the 2 lines where the planet should be. Minor annoyance.
4. Exiting the scenerio hangs the game when trying to go from the stats graphs to the main menu.
This requires the task menu to correct the "not responding" program. Seems to happen more frequently when I launch the game via the Impulse RUN command rather than the Vista games folder, but that is just an impression. Minor annoyance.
I have had issues with Mini dumps on occasion, and the Mines are annoying enough to make me want to just quit playing (thank you, Mr. Ally, for filling my grav wells with your mines?!?), but hopefully these issues are already being repaired so no need to discuss further.
Cheers!
PS: Many thanks to whomever first pointed out how to use a scout to paint the mines for clearance! 
Mods, please move this post to the proper location as necessary. Thanks.
