I click green research button and it opens research..
Chapter 3 has no other advance barrack tech
Is it normal to get a quest that says ready to do and find you can't do it?
I have all resources & space ready with nothing in the red..
What am I missing.. is this a glitch?
thanks in advance for your time
Chapter 3 does have a Barracks Tech. All the way at the end with Main Hall. Superior Barracks.
If this Tech already has the green check, marked, meaning completed... when you click on your Barracks and go to the Upgrade Tab, it shouldn't say "Research", it should only say Upgrade.
When you click on a building and go to Upgrade Tab, if it says Research and you click on it, it will open your Tech Tree and continue from where you are. It will not open Tech Tree and point to where you need to be, to unlock the required Research.
Hope this helps!
