I didn't even know this spot existed
If you can send me some pictures of the map where it is and where you would run to reset aggro, i can probably add it in for you though
Are you able to open the logger next time something happens and see what it spits out? Logger is accessible from the bottom of the client (or top right under settings i think)
I was under the impression that it did act like a queue, did it continue training strength even if you split it into 2 separate tasks? Or could it be that it just didnt swap off strength correctly in the first place
