Will it work if you update r1.1 to r2? will I be missing anything?
In order to update the game from version 1 or 1.1 to 2. first you need to consistently update the version to 1.2. (that is, for version 1.1 you need to install patch 1.2, and then patch 2)
In your case, instead of installing two patches, I would recommend downloading the full version 2. In this case, you do not have to bother with several patches, but simply download, unzip and play. (previous saves and cards are easily transferred through the UserData folder)
Updated from R1.2 to R2, added the optional mods, did the update thing in InitSetting, and now my screen is black when I start the game. Anybody know what's up?
If your computer meets the requirements of the game and has enough memory then. In your case, an update error may have occurred (you may have done something wrong, or the download failed). You need to repeat the update or download the full version. Updating the base build 1.2-2 (without optional mods) through the adapter occurs without problems...
(Adding optional mods can cause errors (some mods require special use).
Version 1.2 had limitations in the work of many mods, there are no such limitations in version 2, and in version 1.2 there were not so many optional mods. Updating through the adapter, along with all the optional mods, will turn out to be quite large. In this case, it is better to download the full version of Repack 2, (in the base build there is also a part of optional mods) additional optional mods if necessary.
This will help you avoid errors when updating automatically. With major updates, it makes sense to use the full version download, especially if you decide to use optional mods.)
