What are all of the "oversights" found in the Pokemon games?

Question

Some examples include:
Psychic-types being immune to Ghost-types in Gen 1.
Fire-types not resisting Ice-types in Gen 1.
Steel-types resisting Ghost- and Dark-types in Gens 2-5.
Poison- and Bug-types being weak to each other in Gen 1.

If there are any more "oversights" that I did not mentioned above, please let me know.
