Haven't touched the core classes, so I'm a little dumbfounded as to why it would be crashing on a vanilla command. I'm assuming I've done something stupid with incorrectly registering my own, custom commands, but I'd appreciate some guidance here. It's a minor bug, but it is also one that crashes the game so... I'd like to get it worked out.

Correct. Now, unless we see what you have done, there is not much we can do to correct the problem.

Hrm. I'll try.

Reveal hidden contents

And all of the commands are empty copies of this:

Reveal hidden contents

Except replace 'scm' with each commands unique tag, including (in order): "checkinv", "checkchests", "createshape", "acs", "econ", "scm", "ccs"

All of the actual command logic is handled in a CommandEvent handler class, where I check to see which command it is by using "event.command instanceof CommandSpecializations" as an example. Obviously all of the others are the same but... that's about all that the commands do. Besides "/help" all of the commands I have work.

Scratch that, just looked at the new method required by commands. I'm willing to bet the '/help' command uses "public String getCommandUsage(ICommandSender icommandsender)" to populate its list- and since mine returns null, it causes an error.

Just ran it and tried the command- it works fine now. Issue resolved.

That was what I expected, since help would trigger a usage event and it would not like to see null. Glad you figured it out.
