Getting the following LUA error when I log in/reload. This is on version 1.5.3

4x ...s\MegaMacro\src/engine/mega-macro-icon-evaluator.lua:243: Usage: SetMacroItem(macro, item [,target]) [string "=[C]"]: in function SetMacroItem'
[string "@MegaMacro\src/engine/mega-macro-icon-evaluator.lua"]:243: in function <...s\MegaMacro\src/engine/mega-macro-icon-evaluator.lua:209>

Locals:
(*temporary) = 119
(*temporary) = nil
(*temporary) = nil`

This is on all characters and is the exact same error for all. Not sure if this is on my end.

It was a trinket macro:
#showtooltip
/use [mod:shift]13;14

I rewrote it exactly like it was, and the errors are gone now. Not sure why the first time caused it to throw errors.

Which macro is triggering this?

Fixed in latest release.
