This issue is listed as fixed by version 1.9.1 released March 30, 2016. However, I am still experiencing it in version 1.9.4. I've built an elevator and while it will work to move up, when going down, these ghost blocks leave me stuck in the middle of an elevator shaft. Removal of ghost blocks leads to falling (usually to my death).
