the core properties definitely disappears if you use a configset, as in ##### #Written by CorePropertiesLocator #Tue May 02 20:19:40 UTC 2017 name=testcore dataDir=/indexes/solrindexes/testcore configSet=myconf
Using a conf directory, as in #Written by CorePropertiesLocator #Tue May 02 20:30:44 UTC 2017 name=testcorewithconf schema=conf/schema.xml dataDir=/indexes/solrindexes/testcorewithconf has the same behavior. This is Solr 6.3.0 standalone, and I share your memory that at one point in the distant past core.properties was renamed on an unload.
