Hello,
First of all let me say that you have done an awesome job, this game runs like Deplomacy should have done. So smooth and graphical improvements look beautiful. Performance is very noticably improved from Diplomacy.
Now to the bug / annoyance i have found. This happens specifically with the titan but may happend with other ships too (only been testing the titan in depth). Basically this is the reproduceable scenario.
Give a titan an attack order on a starbase, or other hard target then manually activate a targeted attack skill, in my case it was snipe. As soon as snipe hits the starbase the Titans current attack order is wiped and it then goes off to attack what ever it likes... usually a bomber of fighter squadren. So basically after every time i activate a targeted ability i need to re-issue the attack order or the titan stops firing at its target.
This has only been tested with the TEC Rebels so far. I will do more testing over the weekend with other ships / factions and see if it is a general AI issue or ship specific.
