: Incorrectly importing files or using incompatible versions of a tool can cause the game to crash. It is an industry standard among modders to back up vanilla game save files before applying any external modifications.
: Modders can transfer players, adjust player attributes to reflect real-life form, and create entirely new leagues or historic teams.
While downloading and using community editing tools unlocks massive potential for game customization, it also requires users to practice caution and responsibility.
: Modifying game files generally breaks the terms of service for online multiplayer modes like Ultimate Team. To avoid permanent account bans, players must strictly use modding tools for offline Career Modes or kick-off matches.
: FIFA game assets are massive. Modding tools use .rar compression to reduce file sizes, making them much faster to upload and download.
