This update is only accessible by switching to our Experimental branches (instructions on how to do so here).
Changes:
Fixed a rare crash that could occur on the strategy layer caused by a corrupted tactical mission. It would manifest as a sudden (seemingly random) crash on the Geoscape.
Fixed a bug that make certain ground tiles non-walkable (generally around the edges of rooms). This was blocking the tactical section of the tutorial, making base defence missions a problem, etc.
Updated the translation files to add in translations for the new text added in 7.20.2, and to fix more translation errors.
