There are some bugs in 2.3 under unreal 4.14.
When creating blueprint for marker emitting, i cannot get structures properly from function node. Looks like unreal does not know types for dungeon model etc.
Also following instructions about starter pack for dungeon architect, how to install it, creates some empty blueprints, but that may be result of above bug. I seen some nodes that were disconnected, with majority of graph missing.
Ps.
Is there a way to get my dungeon architect license added to marketplace, when i bought it on your website?
