Ok i did get some help from someone but It was pertaining to cleaning my computer I am only 18 and i dont know how to even repair a computer, my computer runs fine it is a windows computer it used to have windows 7 then updated to windows 10 a few weeks ago however this glitch or problem with the foals mane and two adult horse manes didnt start happening until i downloaded stuff off of the exchange i have since deleted the modded sims from the exchange but the hair styles are still like this one side of the mane is shorter than the other I would just normally just brush this off but it is so annoying to see this on my horse and id like to start making sims videos for youtube eventually and dont want this on my horse the only problem with the entire game my game even stopped crashing it did that like a few times but then stopped completely. If someone can give me a solution that doesnt involve possibly having to dissect my computer by myself without help from a pro or maybe i should add that i do not use mods i dont even know how to download them so i dont use mods so i dont know what the problem with my horses manes are or how to fix them.
