Mod edit: Currently the latest builds of sourcemod 1.8 (5942) and 1.9 (5984) have fixed any crashing issues. You can download it here: http://www.sourcemod.net/downloads.php
It appears tonight's graffiti update has broken sourcemod. My windows 2012 r2 servers are not starting up with sourcemod, but they are fine without. Running the most current stable version of SM. Anyone else with the same problem?
