>>13991857>>13991857Only because of released pokemon; you can overwrite an HM, then release the pokemon with the HM, and then not have any pokemon capable of learning the HM, while in a location where you can't progress.
The situations where this can happen are more or less limited to Pokemon centers ON ISLANDS, since they cannot be left without surf and/or fly.
You could resolve this easily by making pokemon which can learn surf catchable by fishing on those islands.
Boom, done, now you can't get stuck.
