Hi. From 751 version HB i have lags with auraprocs: CR detect procs after 1-2 seconds. on 750 all works good. Tried code in developer's console: if (SpellManager.CanCast(113858)) { SpellManager.Cast(113858); Log("Cast Dark Soul"); } var sw = new Stopwatch(); sw.Start(); for (int i = 0; i < 100; i++) { Log(sw.ElapsedMilliseconds + " Checking..."); if (Me.HasAura(113858)) { Log(sw.ElapsedMilliseconds + " Detected!"); break; } Thread.Sleep(100); } result: Cast Dark Soul 0 Checking... 99 Checking... 199 Checking... 299 Checking... 399 Checking... 499 Checking... 599 Checking... 699 Checking... 799 Checking... 899 Checking... 999 Checking... 1099 Checking... 1099 Detected! always. I've got ok ping. i'll tried singular and noticed that sometimes got lagspikes for 1-2 second, CR don't cast after gcd and previous cast over.
