mainly wither skeleton and zombie pigman.
wither skeleton still refers to itself as skeleton and uses skeleton's script, and its pictures. when a script points to entity Skeleton, both normal and wither use it. when it points to WitherSkeleton, neither uses it.
zombie pigman doesn't act as if it's enabled, right clicking it doesn't give the missing script error. it also gives this:
[Server thread/INFO] [MobTalker2.InteractionRegistry]: Entity 'type:ZombiePigman' does not have an adapter initializer. Interactions are not enabled.
version 0.6.1 but since it's not yet on the list, yeah. forge 188.8.131.520
