--- Comment #4 from Chris chris062689@gmail.com 2009-04-26 06:55:40 --- I remember someone saying on the forums that it was fixed. They provided a screenshot. http://dragonballshuurajou.com/screenshots/Screenshot2.png I'm not sure if there simply talking about the Alpha Transparency, or the actual Map Stretching not working.
When I tried it in 1.1.18, we still had this bug. I'm thinking between 1.1.4 and 1.1.18 it was fixed, and then broken again. I'll do some more digging into this when I have time.
