Bug#932577: /usr/games/supertux2: Progress on the first world resets after returning from the second world

[Michael Krylov]

Package: supertux
Version: 0.6.0-1
Severity: important
File: /usr/games/supertux2

Dear Maintainer,

I've noticed a serious bug in the game. Basically, what you have to do is:

1. Complete first (ice) world (either by playing or by editing 
   ~/.local/share/supertux2/profile1/world1.stsg and setting all the
   "solved" variables to #t)
2. Go to the second (forest) world. Complete it also.
3. Get back to the first world. 

After coming to the first world you'll stop on the Crystal Cave level,
and all of the levels in the first world will be marked as not
completed. I assume that's a bug, you should be able to return to the
completed levels, although it's a great game and completing it again and
again is a pleasure :)

If you peek into ~/.local/share/supertux2/profile1/world1.stsg again,
you will notice that there appeared a second copy of the first world
list and apparently game uses that to determine your progress on the
first world.

Thanks in advance!
