Steps to reproduce the problem

1. set block (with wand)
2. try to open
3. fail
4. try not to cry
5. cry alot

After restarting the server, this error still comes up

Yes it's a know issue that has been resolved in the newest Beta: minecolonies-universal-1.10.2-0.8.2890.jar

If after installing the latest beta (minecolonies-universal-1.10.2-0.8.2890.jar) U still can't access GUI, then you have to break the hut block and place/build again. Will work again after that.
