@Insanecrusader19 From what I can tell there is a small difference. Hapa's version makes the warehouses OVERBUILDABLE in future eras and nothing else. That means if you want +2 on mines in a new settlement in Exploration, you'll still have to build a Brickyard then a Stonecutter.
JNR's makes the warehouses OBSOLETE in future eras. All bonuses, the +1 food from granary, +1 production from Brickyard, will disappear completely on Era change and be shifted to the City Hall building. All new settlements will automatically start with that +1 Food on farms, +1 Production on mines, as if they all automatically started with those buildings. Whereas using Hapa's you'd still have to build those buildings to get those effects.

hey, thanks for the mod. is there a way to impact save games?

@Hapa , so.... im currently subscribed to this mod of yours.... but ive noticed a similar "overbuild warehouse" mod by JNR... is there any difference between the two mods? XD... i dont mean to be rude to u at all, Im just trying to find out the differences here

overbuildable warehouses stop counting for quarters, right?

Can't wait to use this!! Thanks!

This mod is such a relief !! Thank you so much !!

Good job, on behalf of all civ players throughout the history of time, we thank you for your contribution very much

This really helps in advance start. Ya @Hired Sword i agree world wonders should only be ageless.

Wow, I have been waiting for this :) To make it perfect it would be nice to able to actually choose which building to overbuild. Any idea whether this is possible through a mod?

Thanks for the kind words, folks! @Hired Sword, I couldn't agree more. Warehouses need to have grander effects to warrant being Ageless. Something I wanna explore in another mod.

The more I think about this, the more I think it should be added to the game in a patch. This is how the game SHOULD have been from the start. Ageless buildings can remain thru Age Transitions, but should also be Overbuild-able and Rebuild-able elsewhere in your Settlements. The only things that should be Permanent/Ageless are World Wonders.

Yes!!! Thank you, this was the worst enemy of my citybuilding dreams

Hasta la vista, brickyard!
