Has anyone here experienced changes in their Ancestry.com tree? I have been on and off Ancestry for 10 years and had built an extensive tree with many photos and historical documents attached. Recently, on logging on, my tree only showed my maternal or paternal side- I could not see both side by side. I was advised that there were duplicates, which happens when the two sides are not connected. I've attempted to clear out or merge any duplicates, but the tree continues to dissolve to the point where now I am down to seeing only 6 of the 90+ members in my tree. When I contacted Ancestry support, they advised that DNA should bring up the tree again. I have not and do not plan to do an Ancestry.com DNA test for privacy reasons. Ancestry.com basically said "you're out of luck then". Today I started to recreate my original tree again, and it disappeared again. I had also renewed my subscription to research German ancestry overseas, but am not able to do that either. Anyone else have a similar experience? Any way to resolve, or do I just need to quit ancestry and build by hand?

Convoluted post due to submission rules: I am looking for engineering recommendations for a low cost way to monitor vibrations that may cause structural damage to my 1957 home due to adjacent commercial demolition. Here are the details: home is a well maintained 2 story block home built by family in 1957. The majority sits on raised concrete footers, however I have a room across from the demo work on a concrete foundation(renovated enclosed carport). A multistory hospital (6) floors that covers a city block sits across from my home. It is being demolished. The original demo schedule was 4 months to completion. They are in month 9 with at least 50% of the job still to go. Any recommendations to monitor vibrations for structural damage?
