@xSUNMANx I haven't found a solution to the problem, but I have solutions to stop the problem from happening again,
- Removes duplicates
- Delete Free/To check/2FA when you don't need it
- shrink of your DB from time to time, Tools>Database, do so as well once you apply the tips just above.
- Uses foncton "Save hits to a text file instead of DB (the output
can be found in the Hits/ConfigName folder)" Config>Other Options, when you see that your OB takes a long time to open up
