I'm upgrading a pack to 1.0 but the monsters are attacking very fast. Has the unit for the attack interval changed from TFS 0.4?
Are you able to post here an example monster from your server?

It seems good. The interval is counted in milliseconds so your monster is correct. Maybe it is caused by script or something is changed in your source code.
