Kaivax has posted on the official WoW Classic forums that they have hotfixed two issues today.
One is for Somnus, a level 62 Elite dragon from Swamp of Sarrows. The fix corrects an evade bug when he is being kited over long distances.
The second fix is for a bug where specific macros would pause the swing timer, allowing it to be exploited with abilities such as Slam.
I’ve updated the OP here with recent Classic hotfixes:
January 7, 2020
- Somnus will no longer become stuck evading when he is kited a great distance.
- Fixed a bug that caused /stopattack and /startattack macros to pause the swing timer (rather than reset it) when used with abilities such as Slam.
