Thanks CWTN. I did go through the FAQ prior to posting anything. Although I may have overlooked something and expect a tick box someplace.
You must have a Vindication spell.
- I do
You must have BandoSwap turned on.
- It is
Your progressive spell is treated the same as vindication for the purposes of swapping. So either you have the buff from vindication or DFury it will use 2h
- Buffs previously shown were up when still in 2HB mode. One of those keeping it there? I am uncertain if one of those falls in the progressive category.
The plugin should search for Bando sets that match what it is looking for when...
The plugin turns on
You add/remove a bando set.
When you toggle on BandoSwap.
It should inform you:
That it found a set for bandoswap: "We have bandolier sets and can use BandoSwap!"
- It does
That it did not find a set for bandoswap: "We don't have bandolier sets and can't use BandoSwap!"
Without more information it's hard to know you situation.
I can see one of two bandlier sets in your screenshot.
I can see your current buffs.
I cannot see that you have it turned on,
that it output that it found the sets,
that you have a vindication spell,
that you have two sets of items correctly setup,

and that the plugin swapped to the 2hb in the first place.
- Heading to work, but can grab a screen of it swapping to 2HB this evening. Will spend some time again waiting to see if it swaps back on its own again as well.
Appreciate the help.
