TSM causes errors in battlegrounds

[Multiproc-draenor (Multiproc)]

I have tried this once before and my only solution was to delete and reinstall Tradeskillmaster (TSM). This worked for a while. Bug report:

First time this happened was when I executed a specific macro with salt water potion, on-use trinkets, arcane power etc. I couldn’t find any solution so I reinstalled the addon and thereby lost all settings. Reimporting them cause the error again.
Now it’s back and I can reproduce the error just by using an ordinary spell (no macro).The error appears like 10-15 per second in the chat box (buggrabber addon). Otherwise I would have to click a bug report window endlessly.
I can’t reproduce it outside battlegrounds.
I think I have narrowed it down to a tipping point around Groups/Operations in TSM. I mean. It seems it bugs when I make too make operations somehow. But i’m not sure though.

Anyone? ^^

The TSM website doesn’t have bug report option, so my best shot is here.

[edit]
I have deleted a handful of groups and operations in TSM. So now it works as intended. I wonder how I can send this to the authors of this addon.

[edit #2]
After deleting 5-6 groups and a few operations everything was working fine. then I made a one group and one operation - boom. Error msg returned.

[edit #3]
Forgot to tell it only happens when I play on my mage.
Anyway. Today it bugged me from the moment I entered a BG. 10 errors per second - endless.
So I decided to delete the addon and saved variables, and reinstalled the addon again. Started the game only to see the groups and the bugging reappeared. So I have to delete all files manually after first uninstalling the addon + saved variables + local files apparently…
