I used Mator Smash instead of Wrye Bash for my SRLE LoTD Extended install. Unfortunately, for some reason it causes all horses to be invisible, including those drawing carriages, and dead horses, etc.. See picture below:
I know it is Mator Smash causing this issue, because I have another MO profile that is all identical except it uses a Bashed Patch. The horses are not invisible in those cases.
What should I be looking for in the Smashed Patch records? I've tried messing around with horse records in TES5Edit, but I have no idea what would cause this issue.
