I keep getting lots of errors, mainly when looting and casting on the follower.

This pops up when looting both on Lead and Slave, whether its a mob drop, mined ore, anything that can be looted basically: https://pastebin.com/Fjbp3PJJ

This shows up when using a macro on the Slave to cast spells targeting Leads target: https://pastebin.com/9ZMaE1EQ

The macro I'm using:
/script SetView(4);SetView(4)
/target LEADERNAME
/use [harm][@TARGETTARGET] Fireball

I'm running multiple addons on top of the EMA: https://imgur.com/a/l87nyoU

I'm using WoW Open Box for running dual-box.

Also Slave quest completion doesn't seem to be working, party invites and quest accepts work perfectly fine.
