Problem with Alex's Mobs. Make sure you are using the latest version. If the Mod is already up to date, talk to the Mod author.

Replace the 1 in Level#setBlock with a 3 to update the Block to the client. The Fire is placed on server but not correctly on client.

This is possible up to a point in the debugger since it uses hot-swapping (Intellij im not sure but I guess, Eclipse yes). You cannot modify the class signature (remove/add fields, method, etc), while in the debugger. But you can modify the body of a method (very useful to change parameter/ constants). Your IDE should show your a warning if something could not be hot swapped.

Please post debug.log from the logs folder.
