JSON issue when repopulating name storage during startup

[catbref]

On a second start, the program would not visibly run (it would run in a background for a few minutes (and be seen in a program manager) and would dissapear completely after that)

The log file: "STARTUP ERROR: org.json.simple.JSONObject cannot be cast to java.lang.String
... ERROR Start:37 - log4j.properties not found, search path is C:\Program Files\Qora\log4j.properties using default!"

Still occasionally happens even after upgrade from v0.26.2.1 to v0.26.3.
Looking for a copy of broken database to find out why.
