build queue full - "oh no it isn't"

Hi, first post, playing the game an hour or two - hope this is the right place...

I only have two buildings visible in my building queue - one building, one in queue.
When I place another building it says build queue is full.

All I have done outside the tutorial instruction was to tear down a building after placing it, before it started to build.

Maybe a tutorial bug.
Did you destroy the building while that part of the tutorial was going on?

Another fix could be to try a different browser. From my experience, Firefox seems to have problems, whereas Chrome and Safari (possibly IE9) work fine.

Check this post: Refresh - by Acid_Drinker

Hope that might help in determining if it's your browser, or actually a bug. If it is a bug - contact support.
I think they'd appreciate to know of this problem.

difficult to say, I've built considerably more than the tutorial suggests.
I'll give chrome a try ...
and yes, I believe a refresh did clear the queue problem.
thx for the help

this problem is known actually.

a work around is to close down the building tap wait a few seconds and try to place a 3 building. sometimes that works.

Got the same problem after tearing down a building during the tutorial.
I used "Tear down this building" from the building and not from the build queue and now it's bugged.
