We don't know what the next patc brings so we can't promise it won't give any problems. However, I don't think there will be any problems:
1.) A backup folder is included to undo all the MOD did.
2.) The MOD only adresses the races. If it won't work with the the next patch, delete the 3 new races and reinstall the backup. This will revert your SE4 to a normal V1.19. And! be sure, if the new patch comes out and brings any changes, you can bet that the next MOD pack is right behind it.
