I'm also having the duplicate S-mod bit, along with a decidedly noticeable slowdown then applying vents and capacitors. Shift-click basically does nothing, as it seems locked into its slow/laggy pace.
...I'm not 100% sure that's Concord. There's Progressive S-mod, Carriers, Carriers+, and Better Deserving S-Mods all sorta jostling for position. But I saw the comments about one of the several new bits I'm also observing, and thought I'd start here.
Is there a verified interaction/conflict I should be hounding somebody else about?
I have worked with progressive S-mod and there should be an update soon.
Other than that I can't quite think of the reason of slowdown. Do you experience slowdown in campaign or even in missions?
If it's only slow during campaign it means there probably is some other mod calling everyframe script and maybe struggling or attempting to undo what concord is doing, causing the slowdown. Concord's script is only called when you load a ship, click on a ship or changes something on a ship instead of everyframe. I did not see any slowdown in my campaign or missions, my shift click on cap and vent are smooth as vanilla.
Here is my mod list in case you wonder:

Update: I will make a new patch deploying cached mode to improve the performance of blacklist parsing but at a cost of more ram because the result cache.
