Glass and Greenhouse - Patch

Bug fixes for Glass and Greenhouse by lukeh_ro. Loads alongside Glass and Greenhouse and patches issues without modifying the original. Greenhouses no longer dig a hole when placed. The greenhouse's ground-leveling step flattened the terrain to slightly below the real surface, leaving a permanent dip that also blocked moving or rotating the greenhouse afterwards. The patch now levels to the actual ground height under the greenhouse. Greenhouses built on a raised floor or roof no longer leave colonists unable to reach them. The walkable path through the greenhouse door was being placed at ground level instead of at the floor the greenhouse stands on, so colonists couldn't reach a greenhouse built above the ground. The patch now routes that path at the greenhouse's own height whenever it isn't sitting directly on terrain. Note: the depression is created at placement time, so this patch only prevents new ones; existing depressions in saved games are not auto-restored. Spanish (es-ES) localization covering all of Glass and Greenhouse's in-game text (the Glass resource and recipes, the Furnaces tech, the Greenhouse building and tech, and the temperature infopanel). Requires Glass and Greenhouse and SAD_CommonLib. Version: 1. 00-004
