Failed to init object tables (TBS/TAB)
Issue
After upgrading to v6.002 from an earlier version, the message “Failed to init object tables (TBS/TAB)” appears on the first query request. Further processes do not function.
Explanation
A backup file (city.bak, where city is your config name) is created when editing some of the config files. When the program attempts to update the city.tab file, it tries to rename it to city.bak. If city.bak already exists, this process fails and the update fails.
Solution
Erase the city.bak file in your data directory and try again.
