With the recent overhaul of the testing version, as expected, some things went a bit screwy. As it turned out, the helpful little markers that show you which stars you've been to (highlighted in blue) and which ones you haven't (highlighted in red), had gone off, and stopped showing their colors.
This latest patch fixes that issue.
Major Bug Discovered
In other news, I (with the help of a YouTuber who was playing Star Explorers) discovered a major bug in the default version of Star Explorers. It seems that starting a new game after having selected a saved game to load, will write the new game's save information INSIDE the folder of the selected saved game. This means when you start up Star Explorers, you game will not appear on the load menu.
I may patch this in the default version ... or I may just update it to version 3.6 once I am happy with it. A decision will be made by some time tomorrow.
