(svn r3923) - [Pathces/HACK]: Add 32 empty bytes at the end of the patches chunk in the savegame to not to have to increase the savegame version every time we add one; at least for a while. To not break in-between nightlies a temporary hack is done. So make sure to upgrade to this nightly before you upgrade to newer ones. Releases are unaffected
