This is a small patch with some tweaks to the Horde mode.
The cost for the mercenaries will adjust for the Primal difficulty to 300.
It will remain as is on the other difficulties.
There was a bug with the difficulty not saving on the Horde mode selection with a recent patch, this is fixed.
***Note***
There is a tricky crash bug in the Horde mode that I am trying to hunt down. I am aware of the bug but I am having some issues locking it down as it is not showing up on the logs. I will continue to work on this.
