Getting error when loading or making a new save.

The mod Alert Settings (1.1.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event alert-settings::on_init()
alert-settings/control.lua:73: bad argument #3 of 3 to 'index' (string expected, got nil)
stack traceback:
[C]: in function '__index'
__alert-settings/control.lua:73: in function 'set_player_settings'
alert-settings/control.lua:95: in function <alert-settings/control.lua:92>

There have been some recent changes to alerts and a new alert gui in 2.1.7

Will likely update the mod in future to just open this gui with a shortcut (so you don’t need command)
