I'm a new RTW player and was wondering if the non-official patch v1.2 would be recommended on top of 1.5.
Also the official page also has an updated export_descr_buildings. Would it be a good idea to copy it over too?

I hadn't realised the game was so buggy until I read the posts here. I once exit the game and found a 500Mb zombie which I had to kill manually.
