Cottages lost their upgrades

Yesterday I brought 8 cottages out of storage for the Council event. All were at various levels, with atleast 1 at level 7 and several at mid levels 3-5. Today I stored them very briefly so that I could easily move then to a new location. When I brought them out again they were all at the beginning "cottage" level. They lost all their upgrades!
I've closed and restarted my game twice, with no resolution. Is there a way to get back the upgrades without re-doing them all?
