** Behavioral change: Fix AI heroes sometimes attempting to probe teleport exits using data from a previously processed hero, causing nullptr dereferences. VCAI::moveHeroToTile has special case logic for revisiting tiles. This logic could cause teleport exits to be stored in teleportChannelProbingList, without the list subsequently being cleared. If the processing of that hero ended immediately after that, the next hero would believe that the list is accurate for them and attempt to teleport while not standing on a teleporter.
