This occurs in tactical battles:
Occasionally when I use the tactical battle screen's initiative queue (along the left side of the screen) to click on an enemy portrait, the game treats it as though I am interacting with objects on the main map. Other times it will treat my action as though I've tried to advance a turn in strategic mode, even though I'm still in tactical. When it does these things often various types of dialog boxes and such will pop up in my tactical battle, such as level up information, quest info/completion screens, etc.
When I finally close these dialog boxes & windows the info panel for the monster whose face I was trying to click from the initiative queue is revealed, and when I close that I am unable to see the hit point bars over any unit's head on the battle field, and when attacks occur from either side there are no damage numbers (or misses or status effects) displayed. In a sense I end up having to fight blind, unless I manually start monitoring the health and status effects of each and every units on the battle field by checking their individual info panels.
I am unable to duplicate this 100% of the time, since most of the time I click on the portraits along the left side of the screen the game appears to react as it should, but this is a problem that has occurred on multiple occasions.
There doesn't seem to be any build/resource/time/cost requirements for outpost upgrades when selecting them from the upgrade menu. the only way to actually see these things is to queue up an upgrade and then go to the nearest town and inspect them from within the build queue. It would be helpful if this information was available at the time of the upgrade selection process.
Unit quest rewards:
When I complete quests that result in the gift of a unit to my realm (this has so far occurred with Pioneer and a special type of archer reward), I will not get the unit if my party is full. I would expect the unit to appear in another stack on the same til, or perhaps on another tile, but instead the game seems to go through the motions of announcing the award, but fails to deliver.
