Minecolonies version

minecolonies-universal-1.11.2-0.8.2786.jar
forge-1.11.2-13.20.1.2393-installer.jar

Expected behavior

Able to interact with colonists and chests.

Actual behaviour

Right click on colonists or chests does nothing, occasionally crashes the client. The server has not crashed, and reports nothing interesting in the log. It started when I was running minecolonies 1.11.2-0.8.1784 and forge 1.11.2-13.20.1.2388, which is where the traceback from below came from. I tried upgrading to the above versions, and interaction is still not working, but I've not seen a client crash yet.

Steps to reproduce the problem

Has only happened in my current underground colony, have not reproduced. No idea if it's been triggered somehow by building underground.

Just got a crash clicking on my miner in the newer version:

To leave no stone unturned, I see the same lack of interaction from the 1.11.2-0.8.2797 alpha release.

I've also been seeing lots of messages like below in the logs, about one every minute and a half, which could be related:

[09:59:17] [Server thread/WARN] [minecolonies]: EntityCitizen '564c5893-5d63-4902-803a-a58fa978b9b8' attempting to register with Colony #1 as Citizen #4, but already have a citizen ('564c5893-5d63-4902-803a-a58fa978b9b8')

Okay, so, firstly, are you the owner of this colony or an officer, second this is on a server correct? thirdly i'm guessing the first crash-log was for 1.10.2 correct?

I'm the owner, and only player on the server. This world has only ever run 1.11.2.

@Asherslab I've been largely ignoring the colony for the past week, and playing with other mods in my pack (Mekanism and Cyberware, mainly). I checked if it worked a couple days ago when you asked for more input, and as reported it still failed then. Today I was about to shut down my client, so went to click on a colony chest as an alternate shutdown mechanism, and... it worked. I've not upgraded any mods, nor forge. Nor have I restarted the server. But it's working again, inexplicably. Unless you've had some insight, this will probably have to be put down to a head scratcher, and with any luck never seen again.

Nope, no shutdown, at least on the server side. The server runs on a dedicated Xen instance that I pretty much ignore except when doing mod upgrades. I restart the client semi-regularly.

And, with no warning, it's back. :( I won't be able to debug much for a couple weeks or so. We'll see how it's doing after that...

I tried restarting client and server, no change. I'm already running the latest forge (1.11.2-13.20.1.2393), and upgraded minecolonies to 1.11.2-0.8.3136, still no change. The latest traceback is still a null pointer exception at line 941 of Permissions.java. Then for grins I did a "mc colony refresh 1" and restarted the server, and now it's working again. Hopefully some of this helps. :)
