@Pois0napple: You also need to satisfy the level requirement of the prerequisite units. It's indicated by the stick figure pictures around the build menu.
@TheBoonDock: you can demolish adventurers, build a new guild wing, wait a while to let the game auto save, then reload. At least that's what I experienced, twice, once for demolishing adventurers, once for demonlishing clerics.
@drizzt: it lets you gather up a group/party of units together before they move out to quest. Not useful because it's better to build a unit building and use the first two quests (keep them at low level) to gather up your units.
@LamiaDomina: on a hunch, I saved up more gold until it reached 10x, and was able to upgrade. So I think the last digit or two of the cost probably got cut off due to length.
The numbers have pushed off the screen, it turns out! You're missing a factor of 10 to the displayed number. That should be fixed in the next update coming soon!
Firefox button click issue... slightly fixed. Now for towers, both the left and top edge of each button can be clicked. e.g. lower left corner, upper left corner and upper right corner can usually trigger the button.
Ok think I found the problem. You have an input element on top of the buttons, which I believe is the mouseover text. But this blocks the button from being clicked. For the music / sound buttons, only a small area at the bottom can be clicked. For turret selection, only a small area at the top can be clicked.
Mission timer needs to stop once mission completed. I completed the mission with about 3~4 seconds remaining, see the Completed and score screen then suddenly became a mission failed screen.
Was stuck doing nothing with elves for a while until I saw the comment that hives can switch production. It would be good if dev can add some kind of icon so that we know which buildings have options apart from on/off.
Took me a while to realize the star and number on the weapons was the exp level. Would be good if weapon purchase screen gave some kind of indication of how much damage/ammo capacity/rate of fire each gives. Although to be honest, I basically found the first gun good enough on medium to skip directly to the AK47.
@Pubertie: try clicking somewhere else on the game then pressing the number again. It seems to be bugged if you clicked on some other action in the game like purchase truck/heli before you press the number
 "Guild Quest - Beta"){kind=icon}
 "Bruce's fiery dream"){kind=icon}
 "Shuttle Siege - Light Edition"){kind=icon}

We honestly don't know how that happens so consistently when it wasn't happening before launch -- BUT we have a fix for it coming later today.
