Two of the new quests that disable teleportation don't check if the player leaves in an unexpected way like by using the scripted tribunal ring, they just need to start a gloal script like this one

scripts:

TR_m3_q_TheRiftHappening
disables teleportation and won't enable it if a rift isn't closed

TR_m3_OE_MG_PuzzleExit
disables teleportation and it won't be enabled by
TR_m3_q_OE_MG_VeneDoor_sc
if player doesn't visit Old Ebonheart, Guild of Mages: Top Floor
which isn't so bad but it will also always enable teleportation if it's disabled with no conditions, if some quest tries to keep it disabled from the player later that could be an issue
