the first 3 are obvious.. lol

If you're referring to timebasedincome=false that is definetely right.

TimeBasedIncome=(false default)
Enables or disables the time based income system, keep in mind this is a seperate system to the PlayedTimeBonus system.
true = Enable time based income
false = Disable time based income

If I'm reading your settings correctly, it looks like you're giving 25 ARc every half hour (real time) that the player is in game. Is that not happening? Also, you may want to make

PlayedTimeBonus=True to
PlayedTimeBonus=true (note the lowercase 't' in true).

In programming, 'T' does not equal 't' if an exact match is being compared in the coding.

Your settings are correct, TimeBasedIncome is not needed for PlayedTimeBonus to work.
In this specific case, True is the same as true and you can also use 1.
My guess is you changed these settings after players had already joined meaning they all got set to the old settings. You would need to edit them manually in the admin menu to ensure they are eligible for bonus

I don't mean to hijack or necro threads, but since my issue related to time played currency too, opening a new thread might be overkill.
The issue I have, in single player, is that it does not seem to track time properly. I have set the system to reward 25 ARc every 15 minutes. I'll see the message for a while, every 15 minutes as I have set it, that 25 ARc was rewarded. However after a while (honestly no idea how many hours), it seems to stop tracking this.
And then many hours later, it starts again.

I have calculated that this single player savegame has roughly 105 hours logged as of this writing. Yet the mod has only tracked 14.25 hours...

Is there any reason why played time could stop being tracked intermittendly?
