13410 pin stuck at GND, but simulation ok

Hi there, I'm getting the compile error "13410 Pin led_col_ctrl[n] is stuck at GND" on 15 pins of a 36 pin output vector. When I simulate the design in modelsim these same pins work as expected (i.e. they are toggling, not stuck in one state). I could use guidance as to where to look to find the cause of this error. I've attached my archived quartus project for your reference.

I compiled your project with Quartus II 15.0.2 and did not get any "stuck at GND" messages. Restore your project from the .qar file and recompile it. If the errors are gone then you probably had a corrupt database in the original project. Try cleaning the project (Project -> Clean Project from menu) or just delete the "db" folder in the project folder.

Strange - I tried both downloading the archived project to a fresh folder and also doing Project->Clean on the original project and in both cases I got the same result again.... 

 

I just noticed that you are using Quartus II 15.0.2, while I'm using Quartus Prime 17.0.0 - could that be the difference? I assumed it was something stupid I was doing.
