Yes, I know the map needs some improvements.
Regarding the crown – well, I'm not sure – there are supposed to be 7 lights under the golden dragon – they block access to the crown. By collecting the golden sphere from the cup, one of the lights disappears; you need to collect all the spheres – the crown should then become accessible.
As for the message about the horses – it's another feature of the map (I created a universal script) – the horses refuse to serve you, etc., caused by the total destruction of these very horses by Railag (every creature can rebel if you kill them in large numbers) – this naturally increases their loyalty by 100%.
Yes, I noticed the lights disappearing, but one remained, and there's nowhere else to collect more; all the spheres are extinguished. Okay, let's start over, hoping for a happy ending). And is this the only map with such a loyalty system, or are there others? If possible, please provide a link.
