I found a huge bug
I'm playing as the Silvan Elves.
When i reunited their ancient realm nothing changed: nothing! I got a note which asked me if i wanted to reunite my kingdom and i accepted, but nothing really changed.
Not a new troop, nor new colors or symbols, everything remained the same.
Now, here comes the best part: i got a note that said that the free people of eriador reunited their kingdom so they became Arnor and what happened? I got arnor symbol! The woodland realm symbol remained only in the diplomacy window!
I laugh but it's very... "strange"!
If you tell me how to make screenshot i'll show you that.
