Currently there are two globals in T_D that are used to prevent teleporting. T_Glb_GetTeleportingDisabled is misnamed, and T_Glob_GetTeleportingDisabled should be used instead. Currently, all scripts in TR_Mainland use the T_Glb version, while dialogue uses T_Glob. That is an issue. Replace T_Glb with T_Glob in all relevant scripts via text search.
