SCI: Lighthouse: Bad Palette when stepping out of sphere in Volcano
Game: Lighthouse 1.0c/2.0a
Tester OS: Ubuntu 17.07
I used the same saved game from 2.0a to test lighthouse 1.0c in ScummVM. This is not present in the original game v2.0a, but I don't know about 1.0c.
I played the original game using Jafa's winxp installation. http://www.squirtthecat.com/games/lighthouse/index.html. Which is one of the two options endorsed by http://www.sierrahelp.com/Games/LighthouseHelp.html
If the player takes the sphere in the lava room down a bit then back up when they get out the palette will be discolored. As soon as they click anywhere it gets resolved. Load the save and use the right lever to go up.
