Dismounting horses,donkeys,Lamas,or Wandring Lamas close to Walls or barricades Gets me stuck in blocks

I dismounted a lama or a Wandring Lama that was too close to a building/Skyscraper (0 blocks close to the Skyscrper) I Was expecting to get off the lama where it is But in fact I didn't get off where is was. In fact is got stuck in blocks. I got stuck in the Skyscraper Windows. See attachments below
