Alright, I finally got around to review and fix/balance all the core and civ-specific decisions (if the civ is not listed below in the changelog, it means that all their decisions work fine or/and I didn't change anything to them). These changes do not fix this mod events that will hang your game, turn them OFF in the mod settings file. The maybe-bad news is that I am using VP 2.7.3, the last version before VP 3.X.X for playtesting. If anyone wants to continue to work on this for VP 3.X.X and 4.X.X, please go right ahead.
Installation: overwrite the original files with the ones attached here
Changelog:
1/ CORE:
-General decisions all work fine, just fixed some text and buff Tax Reform decision to give Gold 2x the Culture spent for that decision.
2/ RELIGION:
-No change, everything is fine here.
3/ CIV-specific:
-Morocco: Changed 'Gold from Kill' ability to 'Culture from Kill' ability for Plunder Campaign decision, because the gold bonus doesn’t work. Fixed text description for the special promotion from the Establish the Black Guard decision.
-Rome: Fixed Introduce Concrete decision activation requirement and changed Science cost to Gold cost.
-Germany: Fixed Hanse half build time bonus for Regulate the Zunfte decision.
-Venice: no change. For the Relic of St. Mark decision, I don’t know if the St Mark’s Basilica Wonder ‘bonus culture from trade routes’ ability work (the code for it is too advanced for me and too complicated to test), you still get the free great work item though...
-India: Changed House of Worship decision to only need 1 religion in your empire instead of more than 1.
-Denmark: Removed the ‘8 units’ restriction for Formalize the Thing decision.
-Polynesia: Changed requirement of Revive the Runanga decision from between Industrial-Modern to between Classical-Medieval eras
-Austria: Changed Tu Felix Austria Nube decision to only be enacted from beginning of Medieval Era.
-France: Fixed Grand Armee decision to properly give Gunpower units their special promotion.
-Babylon: Fixed text description of Collate the Star Catalogue decision.
-Shoshone: Changed Found the Comanche Nation decision to cost 2 Magistrates instead of 4.
-Egypt: Changed Establish the Nomes decision to give Gold equal to 2x the amount of Faith spent. Empower Nomarch and Empower Pharaoh decisions deleted because they don’t work properly.
-Korea: Changed Introduce Hangel decision to not require Science cost.
-Zulu: Changed Implement Amabutho Conscription decision to only cost 2 instead of 3 Magistrates.
-Byzantium: Added an extra reward to Establish the Succession Law decision to also give Culture equal to 2x the amount of Gold spent.

-Lastly, all unique units you can acquire through decisions (Great Galleass, Longbowman, Pracinha .etc.) are updated to VP 2.7.3 the best that I can do - such as proper prereq and obsolete techs, proper unit strength when compared to their normal versions .etc.
