I'm not sure if this is an actual bug, but in mining, if you have a wolf traveling between locations and close and reopen the mining tab, it skips the journey and has the wolf instantly arrive at the location they were heading to. I'd assume this isn't intentional, since it makes it very easy to just bypass the journey and make things such as speed from wheels unimportant.
If it matters, I'm on a windows 7 PC, and had two separate windows open at the time of the bug occurring, including the one with the mining tab. I didn't get any screenshots but let me know if getting a screenshot/video of the bug would help, since I could probably reproduce it very easily to do so.
