It's been a while, but I just finally managed to find a solution to an issue that had prevented me from updating the devfiles.
There should be a bunch of new assets and stuff, all of which you can use. I'm afraid I've neglected to make a detailed changelist, but at some point I intend to make some new map making videos to account for new assets and the like.
Anyway, let me know if there appear to be any issues, and I'm hoping to release an update to the Mac devfiles shortly
