Sorry to hear that royjbird. Naturally we'll help you best as we can.
First of all, can I ask you to post your game logs in this thread? This will tell the devs exactly what happened and help prevent such issues in the future. Info on how to find and attach logs can be found in this topic
Once that's done your best bet is to contact one of the moderators ingame (they have the [MOD] tag after their nick in chat) and they will refund you the crowns for the dragon and resources for the units. Unfortunately we cannot add units directly to your city, so giving you resources to train and level up new units is the best we can do.
Once again, apologies for the problems.
EDIT: I see you've made another thread about this problem
and have been contacted by Zvonzi.
