Today I bought a brand new outside SSD, so I decided to move the LOTUS game to the harddisk from my old outside HDD. Unfortunately, I recognised the main game moving is impossible, so I decided to I will move the Content Tool and the Map Editor to the new harddisk. So I went to Content Tool's propertis, I selected the "local files" menu, and after that I choosed the "Move install folder..." menu and I selected the new installiation folder (the old was F:\Program Files (x86)\Steam\steamapps\common and new was D:\Program Files (x86)\Steam). After that, I wanted to move the Map Editor to the new folder, like the Content Tool, but I had an error message ("invalid installiation path"). After that, I wanted to the LOTUS's workable possibilities, but when I started the, I suprised, because the Steam downloaded again the main game. That was starting to get suspicious, so I checked new the folder, and I saw the all game was moved to the new installiation folder (D:\Program Files (x86)\Steam\steamapps\common), but the main game's and the Map Editor's installiation path not changed in the Steam, but the Content Tool's path changed.
My Steam libraries in the settings:
F:\Program Files (x86)\Steam (main)
D:\Program Files (x86)\Steam) (subfolder)
(And my operation system's boot harddisk is the C, which an inside SSD, I don't know if it's important the this information.)
