Today, I found my wood elf female character was laughing very deep like a male character whenever I sprinted while riding any bear mount, specifically tested with Psijic Bear Exemplar and Storm Atronach Bear. She laughs normal while not mounted, with "Voice F" from character creation.
Something is switching the voice while mounted.
2 other bugs related to mounts:
1) Long hair is completely rock hard static clipping through the back and chest while riding bear mounts. This has been bugged this way for at least 2 years and needs a fix to at least keep longer hair from clipping through the back and hopefully make it move like it should and does on other mount types.
2) Psijic Exemplar mounts are not leaving footprint trails behind them, which are normally seen in dirt/grassy areas, unlike the Bloodshadow Wraith Steed and Storm Atronach Mounts that do leave glowing footprint trails. This just changed with Update 19 today 8/13/2018 as I noticed yellow footprints just last night before the patch.
