LinkI guess I've missed when it was announced but they just released the definitive version of this on Steam, something between a DLC and a patch so the game should be fixed now.
(Should also mean it won't update any more.)

Dungeon Defenders Eternity is the definitive version of the hit tower defense action RPG! Slice, shoot and pulverize your enemies, or build defenses to do the dirty work for you. Grab three friends and build a team of heroes from twelve different classes, each with their own defenses and abilities. Then embark on an adventure to defend Etheria from the Old Ones’ army!
Eternity boasts all new missions, new features, a rebalanced endgame, secure online play (no more hacking!), along with a wide selection of content from the original game. Now is the perfect time to experience Dungeon Defenders and its expansions the way they were meant to be played!

And the sequel is getting closer to release.
(Hopefully it won't need as many updates.)
