June 24th Updates
New: If you don't have units with an attack or production buildings you first have to build Barracks/Factory/Airbase/Shipyards before a House or Repair Shop can be built. This should reduce a bad experience where a player builds a house with their only pioneer and gets into an inconsistent state.
Balancing: If a unit cannot be spawned and is blocked by another unit, the unit now attempts to be spawned in an adjacent field. If no adjacent field is available either, the spawn is considered blocked.
Fixes:

Fixes:
- Fixed an issue where spawn effects from optional conditions weren't properly removed in the map editor.
- Fixed various map editor bugs related to effects/spawns.
