Impossible item crafting with beastiary

As a player, I expect to be able to block certain mod groups using crafting bench modifiers. When adding a mod to an influenced item, mods can be added to the item which shouldn't normally be possible to add.

1. Get a crusader belt with two open prefixes
2. Craft "+to armor/+to energy shield"
3. Use the bestiary craft called "add a mod to a crusader item"
4. It is possible to roll "+to maximum energy shield"
5. Remove the crafted modifier
6. It is no longer possible to add the crafted modifier due to the item having a similar modifier

This means it's possible to have two mods on an item that shouldn't be able to coexist.

Expected result:

In step 4, it should not be possible to roll "+to maximum energy shield"

since a couple league ago all the flat defense mods on belts blocked the other mods that shared a flat def stat.

so armour/es craft should block flat ES.

The hybrid mod (armor/es) is blocked by flat ES. If you consider the item I linked in the original post, removing the craft makes it impossible to re-add. Either it should be blocked when adding a mod via beastcrafting, or adding the craft should be allowed when the mod is already on the item. Either the mods can coexist or they cannot.
