Spells: Some magician 24+ research recipes are missing

[mzl0011]

Here are several examples of recipes I have found. I have tested but doesnt work.

I keep seeing where 39 pet did not use a previous 34 spell as the combine recipe, 44 uses 39 and 49 uses 44.

Example 1:

Example 2:

Example 3:

Not sure if this helps any at all or not.
