– Fixed loading of electric network of pre 0.12 saves.
– Fixed blueprint building. Blueprints are migrated as long as you load the version 0.12.30 or earlier, existing bluepritns might be off if you resaved in 0.12.31 already.
– Lua interface to create blueprint now expects the entity positions to be relative to center exactly, so in rail-less blueprints, the position 0.0 translates to center of the tile
when the blueprint is built.
