And that's all I get. No op privileges, no utilities functionality, and as far as I can tell, nothing in the logs. Is there a reason why you can't assume OP for single-player for the player?

For the record, it's not terribly clear that all you have to do on single player is /feiop with no arguments... Still, the question stands, why not just assume the permission on SP?

@Malkierian Are cheats enabled? Running with no args means running only /feiop.

If cheats are enabled and you're in creative, you should be auto opped. Though sometimes it takes some time before it auto ops you after opening a world.

Yes, I know what running with no args, but the instructions on your Forge page don't say that clearly. /feiop (single player/lan) didn't mean only /feiop to me. I was trying to put in "lan" or "singleplayer" or whatever as an arg XD

But, I wasn't in creative, I was in survival, so I guess that explains not auto-opping. I just figured, since the whole point of it was to have a few cheat-like capabilities, that user management would be a non-issue if it's single player.

So is everything working now?

Yes, it works, though I would request some clarification in the instructions.

Ok. Will take this into account.
