I have removed mods from the save, loaded into it and tested the layouts, it looks like I can plumb the sinks in any of the layouts you mentioned. This would likely mean that one of your mods is likely causing the issue, since I cannot replicate it on this same save without mods, unless I misunderstood the issue?

Honestly I forgot this menu even existed, I've just been using the default "add (xyz) to (zyx)" and haven't felt the need to use the new menu.

Your graphic drivers look out of date, which may prevent the game from properly launching. I suggest updating them from your CPU website: https://www.intel.com/content/www/us/en/products/sku/75104/intel-core-i34000m-processor-3m-cache-2-40-ghz/downloads.html
