This is not a fix, but a fun
Since I haven't been able to make a stable 0.6.2 server from 0.6.2DR1 release source code, I did a quick hack in current CVS (developper tag, Oct. 6 2005) source. Result is, well, pretty much stable
The hack is not a big deal. Modified file is just one, common/database.cpp, stopping to SQL-search for non-existing columns (like INT, CHA...) from 'npc_types' table.
Set -DCOMPAT_062DR1 in your makefile* and recompile.
And, you'll find something new in guards
