The bulk update request #12500 is pending approval.
remove alias tankmorph (0) -> living_tank (238)
remove alias tank_morph (0) -> living_tank (238)
Reason: Tankmorphs are different from tank_humanoids the same way anthros are different from humanoids, or aeromorphs are not aircraft_humanoids, and not the same thing as living_aircraft (see topic #46539)
Followup:
imply tankmorph -> living_tank alias tank_morph -> tankmorph
