So, this is interesting:
I disabled all other addons, and now I get the same for both cases:
Code:
1551.817 SetItem
1551.85 Cleared
1551.85 SetItem
1552.051 Cleared
1552.051 SetItem
1552.252 Cleared
1552.252 SetItem
1552.453 Cleared
1552.453 SetItem
1552.654 Cleared
1552.654 SetItem
1552.855 Cleared
1552.855 SetItem
1553.057 Cleared
1553.057 SetItem
...
What does this mean?
