Sorry for inconvenience. Currently DLC should work fine.
I'm running 1.1.3o on Linux, and while a new game DOES show the male Tiefling protrait, the portrait is NOT shown on the right hand side with the other protraits, and neither the Tiefling race nor the Kineticist class.
Installation order was:
1. Game itself
2. Pre-order Bonus Items
3. Bloody Mess DLC
4. Wildcards DLC
The only difference is that 1.1.3m didn't show the Tiefling protrait pre-selected. Note that none of the workarounds described here seems to work for me.
Oh, and also, libAkSoundEngine.so still seems to be the wrong version and needs replacement!
