0.6.5 crashes and bugs in mod menu

I corrected the title of your topic as you are actually just playing 0.6.5 and not 0.6.6.

I assume you installed a mod through Steam? Could you tell me what the path you have installed Steam into is? The error seems to be about there being an incorrect character in the path that the game doesn’t like.

As 0.6.6 is switching to a different .NET runtime and a much newer version, it might just work. Could you try the new RC early build to see if that works for you:


Update: I’ll add some code to the 0.6.6 release which will not load a mod icon if the path creation to the icon file fails, this should prevent the specific error you got, but likely won’t fix the underlying cause.
