So I recently opted into the 1.5 beta, started using mods and got this: Now, I know I like mods and stroking my ego by getting achievements, so I did a little digging. When you start a save file with mods, the game marks your save with the [M] prefix. I figure the game just adds a tagline to your save data but I couldn't find it.. so I tried doing a console save (this would require re-enabling the console in the beta, which is already a mod that can be downloaded in game): > save SAVEFILENAME and got this: It seems by saving via console, it got rid of that dreaded '[M]' tag... but I already have all the achievements and can't confirm whether this works or not. If anyone gives this a try could you let me know if it works?
