Reno will only be your probably problem with the Gov Villa and Dojo, as they would only produce military units of whatever age the building was still in at time of collection. Town Hall automatically ages up to the new Era as well as units {only if you have the Unit Emissary(ies) selected}. If you did have the proper Emissary selected and have done a couple of collections, but no units (unattached only) available, then you may have an issue for Support to review.
Btw - if your Villa and Dojo were only one age back, it is best to use 1-Up Kits instead of Reno Kits, since Reno kits can upgrade multi ages at once, whereas 1-up (as the name itself implies) only ages one Era at a time - of course, only best if you have 1-Up's in inventory - or hope your 7 day Daily chest award will give them to you,
