The patch does improve treasure the treasure generating algorithm, one of the effects is those are less frequent. I asked people on the forum and the consensus was to include treasure generation changes.
You can still find them but you probably had bad luck with it. Considering the unpatched game had like 10 of them in every map, they were so frequent, luck was not really a factor.
More importantly, treasure is generated at the start of your game. Reloading and fighting the same place again will give you the same category of treasure, so if the map was low on these when generated, no matter how many times you try reloading, you won't get more of them.
If you don't like these changes, you can apply a reversion to the appropriate patch files and then apply the reversed patch to remove the effect. All the treasure related patches are starting with an "M", generally having a low number, and the files have a description in them in plain text so you can find them easily.
I don't really recommend removing them though as being able to find a dozen books and specials each game really devalues your starting choices, also note the AI can get the treasure so having more high end treasure isn't necessary to your advantage.
