So after last maintenance I couldn't help but notice that some of the fences that were previously added to help fast horses autopath w/o getting stuck/running offroad/into rivers are strangley missing - more specifically the ones on the bridges next to Heidel.
I have not went to the other popular locations where you would always get stuck (like the bridge near Red orcs) and I have not seen anything mentioned in Known issues or the patch notes about removing those, then again why remove something that is meant to help with autopathing issues.
You might want to look into that and put those back in place. Getting back to your horse drowned in the river during autopath isn't fun.
Cheerio,
