I launch a rocket, I get an error message like this in the game.
This was the same result if I put in a satellite or another item.

Error while running event RPGsystem::on_rocket_launched (ID 10)
RPGsystem/control.lua:973: attempt to perform arithmetic on local 'r_count' (a nil value)

I checked the 973 line, But i can't found anything wrong point.

Ps'
I used a free translator, so it may not have been translated correctly.
But please send it to the manufacturer accurately.

Ps'2
Thank you for making we a nice MOD!!

Ps: did you change player name in your game ?

Thank you so much! Now, I can launch a rocket!
I have never changed the player name. ( I mean, I use only this player name)
