Good day. I've encountered an issue with TMW sometimes stops working partially, and exactly some groups do not work and some of them are functional. 
This happens when I log in to the arena. 
I've found this particular post and it seems like I have the same problem.
https://wow.curseforge.com/projects/tellmewhen/issues/1540

I've clearly understood that this cannot be solved due to some blizzard restrictions, however, I'd like to know. 
1/ Is there a specific way for me to build my groups so that I can avoid an issue?
2/ If I simply /tmw twice, will it fix the issue?
Thanks for the reply in advance!

 I had this error too. I found that owner TMW fixed in some one latest github build. If you want fix it you should check "Condition" tab in group/frame control where you probably have missed (empty) condition which cause you error, I found 1 frame which wasn't enabled as "type" and he had some conditions inside. I removed them and it started work.

Well, I've checked everything and could not resolve the issue.
I've also uploaded a full export of my profile(all the global groups). 
Here is it - https://pastebin.com/1NVUTfsR

The thing is - I'm not checking spell charges of 77762 (Lava Surge) anywhere. 
I'd be more than happy to get rid of this issue.

Btw, I've found that if I /tmw twice in the prep room when the issue appears - tell me when works fine.

This is indeed a duplicate of many past issues, but most recently https://wow.curseforge.com/projects/tellmewhen/issues/1572 as it relates to the issue happening when zoning into an arena. This issue should be fixed in the latest alpha: https://wow.curseforge.com/projects/tellmewhen/files
