Hey @Irishnin9, thanks for reaching out and bringing this to our attention.
So that we could look into the matter further, may I check the following:
- Did you notice whether issue occurs in particular locations or does it happen through-out the map?
- Did you see any terrain in front when horse stops the full sprint, or is it the case where it can happen in a plain field?
- Since when did you notice issue happening?
- I take it that the stamina bar when this occurs is yet to run out, is that right?
In the meantime, if you do happen to have video footage showing this, it would be great if you could share it with us as it will be useful if in need for reproduction.
Let us know!
