Does it still work? I'm looking for a similar mod but I'm struggling to find anything up-to-date.

Updated to 3.10

Finally! I've been looking for a mod like this for weeks!

Just meant as a suggestion, not a criticism. Good point about the tooltips though; I hadn't thought of that.

One could make a similar criticism of almost any mod that modifies existing content. That's just how Stellaris mods work.

Also, changing the additive modifiers changes the tooltips. This is how I personally like it to look when I play, so I'm much more likely to update it.

It looks like your approach was to find every instance of command_limit_add in the game files and change it. That works, but it may create compatibility issues whenever a future version of the game or another mod modifies those files or adds a new instance of command_limit_add.

According to the Wiki, command_limit_mult is a valid country modifier. The only instance of command_limit_mult in the base game is admiral traits.
