I had to recently reinstall my Nraas mods due to unrelated game corruption, but now whenever I want my horses to try for foal, it's grey and says progression denied. I've had another look through all of the settings and can't seem to find which mod (I assumed it was story progression, but also checked woohooer and the general master controller), nor could I find an individual setting that would be blocking it.

I know it's probably a really obvious setting somewhere that I've overlooked, but if anyone could point me in the right direction, I'd really appreciate it!

Hi Robyn, and welcome to NRaas. Progression Denied does indeed mean StoryProgression. Often it's a caste setting that trips these things up. But sometimes, especially after travel but it can happen other times as well, the link between Woohooer and StoryProgression acts in unexpected ways. You might try breaking the link to see if that works better for you. On City Hall or an in-game computer, NRaas > Woohooer > General > Link to SP > False.

In fact, the next version of Woohooer currently in beta testing has that link set to False as its default since it acts up for so many.
