The game tries to send you to a certain spot on the map when you choose to adventure with the collar, but if you go through the text too fast it will still try and make you move to that point after entering the new area, which isn't possible. It should have eventually just made you stop moving when it realized getting there was impossible, but for some reason, it didn't. In any case, this patch should prevent it from happening in the future, and also contains a fix that should get your character out of that movement loop if you have a save with them in it. Just need to load the save and it should automatically stop your character, if it works correctly. https://mega.nz/file/RO4H2KCZ#WIrNoLapNcAXILwJxNlwaqBpIQwJVs00mT7dSgqHWPo
