I got the following error when logging in:

1x Kui_Nameplates\plugins/execute.lua:146: attempt to index upvalue 'EquipScanQueue' (a nil value) Kui_Nameplates\plugins/execute.lua:146: in function 'func' Kui_Nameplates\messages.lua:165: in function <Kui_Nameplates\messages.lua:145> Kui_Nameplates\messages.lua:220: in function <Kui_Nameplates\messages.lua:214>

This error only occurs when Enable execute range is disabled in the options.
Only happens at the first logins after the game client started.
Here is an example:

1. Starting game client
2. Logging in with first character - error
3. Logging out to character screen, logging in with other character - error
4. Logging out to character screen, loggin in with first character - no error
5. Exit game client
6. Start game client again
7. Logging in with first character - error ... and so on.
