I never noticed that two streets in Groddle Meadow have the exact same background layers and platform designs. The only difference is the foreground objects and sign posts. Both streets even have the same Shrine to Tii.
Surely one of these streets was meant to have a different design but somehow was overwritten by the other street? No two streets in Ur share the exact same background combination... If so, will we see the real visage for the suppressed street before the end?
The two streets:
Eglesgown Wanks
Greenvern Mend
Update: moucri has made some further observations.
Briarset Croft is also essentially the same as Eglesgown Wanks and Greenvern Mend.
and these two streets look the same and both have Shrine to Mab:
Brinlow Vale
Welldale
Update 2: Hburger has the answer! http://www.glitch-strategy.com/2011/11/a-look-back-street-upgrades/
