Full Changelog: Alpha2...Alpha3
Alright, big stuff that looks small:
The assetbundles no longer freeze the game when they are loading.
I managed to utilize the in game prompt system to hack together a loading progress dialogue.
I'm still slowly deconstructing the buildings to make BuildingSetup.cs. That'll be really nice to use in Unity when it's done.
Once again, keep having your fun playing around with custom maps.
