well this just happen to me also. i saw before i unlocked city expansion #5. it said in the expansion section -1 city expansions. not thinking much of since i am very new to the beta server when i unlock my city expansion 5 it just went from -1 to 0 "even" and never received my expansion for number #5 on the research tree. which sucks cuz i am very small city just started. so its a big deal not to have that space to upgrade or add new factory's, especially after they just made me go back and use more then a full expansion researching the academy and then forcing me to build it also, so i already lost a lot of space doing that about 3 days ago and haven't been able to doing anything until i unlocked the next city expansion"#5", except i got robbed and never received it do to this bug. so here i am stuck and cant progress on my city cuz i was forced to build the giant academy that i thought was optional like they said when released. then i worked on unlocking city expansion #5 to finally move on from that and start building again, but nope.!!!!! so my question is how long is it going to take to receive our missing expansions we never got after unlocking them????? cuz i am at a stand still until this is figured out, which really sucks....! This needs to be fix asap please!
Then i see the first post on this thread is from march 16 and its now the 23rd. so its already been a week since some people have not got there expansion. so how long will this go on Elvenar? this really puts me at a stand still with a city like mine that is so small...! and i a sure a lot more people also! i understand its beta, but we cant just twiddle our thumbs and not build.
