Hi there! New to GOG, don't know where to go, search function doesn't seem to work? My game, M&M: WOX is crashing on using the town portal spell, don't know why. Any assistance?

Maybe try the game's sub-forum, you might find some answer there.

If I'm not mistaken, this is a known bug that happens when you cast the spell from an item. Casting the spell normally works fine.

I'm not sure there is an official solution, but I vaguely recall there being a fan-made mod that fixes it, as well as other bugs.

Once you're powerful enough to cast the spell normal, this shouldn't be an issue anyway.

That's wonderful, thank you! Glad to know.
