It's been ages since I was last active in here, but finding myself getting into the Total War games again, I decided to give this mod a go. I noticed some years ago that the map was a bit off thanks to the vanilla version. The Moldavian region was given to the Russians. Problem here was that a part of it was indeed Russian (Basserabia), but the city on the map (Iasi) was Romanian. It is clear that the Romanian faction faced little love from the developers, but that is completely understandable. You can not though only give Romania one province in this situation, because in order to take Moldavia, you need to attack the historical ally, Russia. Also, Romania has no means to do research, but with the addition of Moldavia, you can build a town and start an university there. Unfortunately, that was bugged and couldn't actually do any research, so I fixed that too.
The mod is known to have some issues with the crashes at the end turn, but as of now, I had no crashes with my changes. I gotta admit that I've played a bit with the unit sizes too. I started the campaign by mistake with small sizes, and because I only focused on buildings, I only observed the small size of the units by 1915, but seeing that I had no crashes, I decided to change that too ... so I played a bit more with the files and now the save game I will post down there will have huge size units, and still no crashes (right now I'm about to enter 1917 and no crashes).
I will post there all the files I edited in order to make Romania a better country to play .. and I will post the savegame from 1915 too, in case you don't really want to modify the startpos file.
Take note and make copies of the files that you are putting my files over.
_GreatWar5_DB_Tech_Effects -> you put that in Napoleon Total War/data/The Great War/Files. (This fixes the game so the universities can actually research in the minor countries)
---Romania Early June 1915 ->thats the savegame, you put it in the save_games folder. Appdata/Roaming/The Creative Assembly/Napoleon/save_games. You don't need this file in order for the fixes to work.
EDIT: startpos -> this is an updated version of the above 'fixed Romania ww1' file, which adds an university for Romania at the start at the campaign. You unzip the file into Napoleon Total War/data/campaigns/ww1_main.
Once again, make copies of the files you are overwriting with mine! I am very far from actually being a modding capable fella'. For the most part, I just followed guides in order to achieve this, and I thought that it would be a shame to leave this little work just for me, because I think many people run away from these little things, but might still want to enjoy the tweaks.
TL;DR -> These files are giving Romania the Moldavian region and fixes the university not being able to research anything.
