For users with Win10 operating system uMod v2 r49 isn't working, the game crashes while loading before you can even inject some mods.
uMod v2 r51 is working, but not fully. Out of four mods I have made, only one shows in-game, so it's limited how many mods are actually going to be visible with this version of uMod.
At least I've finally been able to wear one modded costume in the game, here's a screenie:
But since I have Win10 and uMod v2 r49 is no good for me, I won't be uploading mods for others to use until there's another solution for getting them to work in-game.
