Turns out the last screenshot was because I left the "ECLIPSE" line totally blank thinking it was referring to the online eclipse towers. As it turns out, leaving a group blank forces the game to spawn zero traffic, and Construction Peds by default.

I may have ballsed this up slightly

It's been a long couple of days, but I've got it working quite nicely now. I have a few little things to tidy up, then I need a new/additional ReadMe file to explain how the popcycle generator works.

I've got the generated popcycle and popgroup both running in my game now, and they are working very well. There is an FPS hit if you take the piss with the amount of different popgroups you have, particularly if you've got several in the same schedule area. I'm running an i5 with a GTX1050ti and 8Gb RAM, with a shade over 1000 vehicles in the game, and have gone from consistent 60fps to mostly 60fps with lows of 40fps in densely populated areas.

I think there are a few things in both files that are beyond my current understanding, that could improve things massively if changed, however to maintain reliability I have left those parts well alone

For one, you probably want to post this is into Installation Help & Troubleshooting, not Off-Topic.

For two, if you have the links to everything you want installed, then just install them, all good mods will have a readme file with installation instructions.

For three, with an attitude like that, no-one is going to want to help even if you do struggle with the simple installation instructions.

We need a lot more detail if you're going to get any help. What gameconfig are you running, do you have the required mods installed, have you got the packlimit adjuster, heapfile etc, what vehicles are you trying to add? Its impossible for anyone to tell you if a replace car will also crash your game
