When I mount, the defined set is equipped.
When I unmount it doesn't switch back to previous set.

It's really weird.
It doesn't work on my hunter with the raptor, but it works on my warlock with dreadsteed.

Already deleted SavedVariables for my hunter. Didn't help.

I was having issues with the main set not going back on after the mount set even after the ammo slot workaround. I equipped a tabard and found that it started working (for the most part). There are still times when I get in combat with the mounted set and it doesn't swap back when combat drops and I dismount.

I guess I need to follow up on this if I have a valid subscription again.

Let me know, when I can help you testing.

Thanks :)
I guess it will not be in the near future :/

Retest with 3.37 please, disble all other addons and move your (complete) WOW folder out of the way.

I have 3.37 installed. Still didn‘t work, but I have to test it with Folder WTF and Interface removed.

Everything is working on my warlock, on Hunter it doesn‘t. Swimming scripts f.e. is working well. Can‘t test it on other chars, since no mounts on them at the moment.
Also have to test location based events, if I see a difference.

I will do this this Weekend and let you know.

Did it fix it?

So, I've tested this on a fresh install with no other addons installed.
Unmounting doesn't switch back to previous set.

Yes! This workaround fixed the problem on my hunter.
So then this is only related to classes/chars which are using items in the projectile/arrow slot.

So it still does not work on the hunter but works on the warlock?
Which item are you trying to equip/unequip? Is it the same item on both characters?
Which mount are you using? Is it the same mount on both characters?
Which server/ character?
Average latency?
Does it work if you dismiss your pet?

Also a comment from curseforge:
I am having the same problem as some on here, I have itemrack set to equip my carrot when i mount...and it does equip it but when i dismount it will not change back to my original setup.
The frustrating thing is it works perfect on my mage but will not work on my rogue, I can manually change between my pve and mount sets
I have tried disabling every other addon and just use itemrack but it will not work on my rogue
I have even tried to move my WTF folder and it still refuses to work on my rogue
I have reinstalled itemrack and done multiple /reload and still not working

EDIT.....FIX

Ok so possible fix for other people, If i don't set anything in the projectile/arrow slot on my mounted set this works perfect, so to get this working go into your mounted set click the projectile/arrow slot to turn it off and hit save...I hope it works for others as this was driving me crazy trying to workout what was stoping it from working

Can you also try this please?
(I still don't have a WoW account)

When you create a new set, is the projectile/arrow slot automatically enabled (unlike the other slots)?

When I create a new set, I'm already on an existing set, so I just change the name and save it with new name. Is there any way to create a new set from scratch? Except when having a new install? How could I test?
What I found out about the projectile/arrow slot also, from time to time it get's lost in the set (if ToggleAll is enabled).

I also found out that I used the plugin in a wrong way. I always used ToggleAll.
Since I only want to change one or two items (carrot f.e.) it makes more sense to only enable related slot. When I enable only related slots, then I have no more problems.

Following problem when addon gets loaded.

Can you elaborate when this happens or have a closer look?

Can you test this branch please and check if the ammo slot bug is fixed now:
https://github.com/Rottenbeer/ItemRack/commits/fix-ammo-slot-mount
Thanks :D

@philb74 I updated the branch, do you mind to check again please?

I see no changes on the branch? did you commit?

@philb74 I force pushed https://github.com/Rottenbeer/ItemRack/commits/fix-ammo-slot-mount

@Rottenbeer I tested latest version and still get following error.

@philb74 can you retest this on the newest version 3.64 please?

Since you are linking to here for the mount set issue. I had to delete the event I had previously and recreate the event to get it to work right. The issue just started happening today and that was the only solution.

@Rottenbeer tested it on 3.66. It works well now. Thx!
