I get an error from Grid every time I cast a renew or if anyone else in my party or raid casts a HOT spell. It only happens the first time I cast one after logging in or zoning into an instance and then doesn't seem to happen again. Seems a bit strange. I have a ton of addons so rather then disable them all one by one and see if there is a conflict I thought I would post the error here and see if something stands out or if this is a common problem. Thanks!
Hmm...after seeing it copied here it was more clear to me that it might be a problem with Grid HOT stack so I removed that module and it seems OK now. I'll test it next time I raid to see if the problem goes away but for now it seems fine. Trying to remember the difference between HOT stack and the regular HOT counter. Is the stack one just meant for druids and it was causing an error because I am a priest?
