don't know if it has already been asked this (in case, sorry for the repeated topic), but... yesterday evening I was playing the scenario 9 of the league - which means all expansions mixed together - and I had a Hound of Tindalos appearing in Kingsport. After a couple of rounds, a Mythos card instructed us to move this monster, but there weren't investigators in Kingsport it could hunt for. Should the Hound of Tindalos have been able to reach investigators in Arkham / Dunwich, or remained confined in Kingsport? I don't think monsters are able to catch the train and move, and only aquatic monsters seem to have the ability to reach Arkham, but considering they have a special movement, I'm not that sure.
Thx for help
