Make sure to follow all steps, including making backups. And try this out first as a test, not as the game in which you will immerse yourself. And then please report back re anything significant.
1. Make a backup of your teams.csv file (found in your ...data/stats folder)... just so you have it. You won't likely need it.
2. Replace your teams.csv file (in your ...data/stats folder) with a custom one that changes all references of Guardians to Indians (attached; open the zip file, rename/copy the csv file to Teams.csv).
3. Make a backup of the modified teams.csv file because when OOTP updates, I believe it will overwrite this file. (Or simply save the attached file - Teams - cleveland correct.csv and copy & rename to satisfy step 2.)
4. At initial creation of your game, manually change the nickname from Guardians to Indians. (This should be the only time you will need to manually change the nickname.)
5. Be aware of when OOTP updates, and when it does, repeat step 2.
Note: It's a free country, but please do not reply with any comments & opinions on whether the name should've been changed by the Cleveland franchise, Larry Dolan, MLB, etc.. That - which has been exhausted elsewhere - is not the subject of this thread. Rather, it's merely to suggest a workaround for those who like to do historical games and would like to see the Cleveland franchise with it's historically-accurate nickname. (Otherwise this thread will get closed and we won't be able to comment on the actual steps & file, and how it's working out
