Just an update. Few days ago I was playing around with my files and decided delete my OSBUDDY saves and all tribot saves including all installs. After I decided to re-save the file Einstein kindly provided for deleting hooks. I re-ran this a couple of times, pressing 2 (no) each time when prompted if the Runescape client was opened. I have also played around with my drop down settings in data, so may be I accidently did what you're describing in the post above.
Either way - I haven't had the issue since and can bot for period of up to 15 hours with ease of mind.
I can't confirm which action it was that fixed it, but re-running the hooks deletion more than once definitely seemed to do the trick.
Hope these steps can help others - though I know it's not concise.
