- Fixed a data error preventing the Sacred Vault to be built in cities where an Arcane forge was already built.

Fixed missing icon on the unit property given by Sacred Vault.

- Library is now required to build Grand Palace instead of Observatory
- Added the Jeweller upgrade for Mana Fuel Gold Mine- for those playing with the Ayalin premium Dreadnought mod

Fixed Home of Orphan Animal and Abandoned Kennel spawning a unit every turn.

They now only spawn a unit the first turn.

Pretty big update to the mod :
- Added 8 mystical city upgrades linked to shrines
- Added 11 new city upgrades linked to the different races of the game

Grouped all the content of the mod into a new Research branch, which will allow you to choose when you want to have the different upgrades available based on your current state of development.

Giant Bean and Garden of illusion were not having their proper unlock conditions and were available all the time.

It's fixed now, sorry for that.

Some small balancing changes :
- Kitchen garden now gives +5 hp to tiers I & II units instead of +3.
- Well of soul now gives +60 morale bonus instead of +50.


Three new mystical upgrades :

- Giant Bean - requires Leprechaun garden & Kitchen garden - 100 gold / 50 mana
Tiers III & Tiers IV units produced in this city get +10 hp. Incorporeal, Machine and undead are not affected.

- Garden of illusions- requires Leprechaun garden & Florist Shop - 50 Gold / 100 Mana
Tiers I & Tiers II units attacking this city suffer a -250 morale malus. Machine & Undead are not affected.

- Jeweller - requires gold mine - 50 gold
Increases gold production by 25%.

Dev note : Jeweller is replacing Underground funnel as the dedicated mystical city upgrade for the gold mine structure. But Underground funnel is not done yet, it will come back differently in a future update :)
