Couldn't say as I've only been using the one save from the start so far. But as I said, the trainer is always a little twitchy when 1st used after loading a save, even before the patch. So a new save may be better, but may be no different.
The issue with easy kill on other monsters is fixed in next trainer update
The new trainer had not been uploaded yet. Now it has.
Gettin slow in your old age eh? LoL 😁
