Multiple Item Bug Fix

Hello everybody!

It seems that I forgot to publish this blog post and didn't notice for 25 days. Well, anyway, here it is:

This update just contains two bug fixes. When a node needed more than one of a item type to unlock it wouldn't work. I fixed that issue and now nodes will be unlockable. Additionally I fixed a crash.

Have fun!

* v1.2.2
* Bugfixes:
* - fixed a bug with nodes that use more than one of a item/weapon/armor to unlock. These nodes can now be unlocked properly.
* - fixed an error with cost info window that happend when an actor didn't have a tree assigned. This now works properly.
