I am fairly new to this game but, I do enjoy it as well as the other games in "The Last Stand" series. I have been playing for a couple of days and and recently reached Level 7. Here is my info in the game. (User ID)
I am get the "Invalid building" error. It happened after I sent my recon man alone to clear a Level One home. As soon as I hit the "Leave" button I saw the message. So I read the message and closed it, but then I saw it had marked EVERY building and I could not move them to a "valid position". I have tried reloading the game but to no avail. it just starts and pop there goes the message.
I have some screenshots linked to this post that show the error message along with some shots of a Zed attack being repelled while I was trying to figure this out. they are in chronilogical order, I hope this helps, because I would like to get back to playing the game.
#1:The Error Message
#2-#5:My Compound, Showing all the marked Buildings.
#6-10:The Zed Attack, All the Buildings are there but, this is just a PvE Attack.
#11:Right After the Attack, all the Building are Still Marked.
P.S:I still have a couple of days of "Beginners protection", just so you guys know.
And Finally, #11:
Again, With Respect,
