It's not working for me at all and says the same thing. The mod loader tries to load the game but then just crashes the game. Looks like all my Mods are doing this..... I guess that's what happens when you use mods huh.. Crap.

I am having the same issue. realy disapointed now. Back to vanilla I guess.

Works absolutely fine for me.

There is nothing wrong with the mod. it works with 1.25.5.2. did you have other mods enabled alongside with Synergies? If so you might wanna move Synergies on top of your other mods. Likely a conflict with your other mods if thats the case.

@devil I have 1 mod, synergies, it loads initial title screen for about 2 seconds and crashes.

aint working for me either

This is all because someone decided to update Torchlight 2 with some freaking translations.
If they didn't do that, you wouldn't have any issues running Synergies.

My only guess is to find someone who knows more about modded games and the twichiness of updates.

I'm pretty Runic Games doesn't really exist any more, so I don't think it was them.
