I just loaded a game with this mod and already got this bug:

Error while running event helmod::on_load()
A script command already exists with the name: helmod stack traceback:
‗ ‗helmod‗ ‗/core/Command.lua:17: in function 'start'
‗ ‗helmod‗ ‗/controller/EventController.lua:99: in function
<‗ ‗helmod‗ ‗/controller/EventController.lua:97>
stack traceback:
[C]: in function 'add_command'
‗ ‗helmod‗ ‗/core/Command.lua:17: in function 'start'
‗ ‗helmod‗ ‗/controller/EventController.lua:99: in function
<‗ ‗helmod‗ ‗/controller/EventController.lua:97>

U run this mod with original mod?
only one mod can run

Don't you have a conflict specified in info.json?
