This is an option to solve most of the corruptions to the knowledge base that might occur due to some more exotic knowledge engineering.
Run this tool when Quaestor provides a message that your knowledge base has been corrupted. If you can repeat the actions that causes a corruption, please inform Qnowledge so we can solve the issue. After selecting the option, you will be informed by several messages about all different type of corruptions and whether Quaestor was able to solve them.
