I am the owner of the vending machine, when I crafted it, set it up and opened it - I can’t start adding goods to it, to do this I need to restart the game or the server (tested on the server), there is no menu with the display of goods after the first installation!

Please provide the game log where you did exactly that.

Also if possible will be addressed in the next patch.
Though there is now a AT LEAST 4 weeks delay until the next patch.

I don't have logs, I don't know where to get them from, try it yourself.

@MrJorman there is a "logs folder" on the server which contains the "latest.txt/debug.txt"
And I need them from you because YOU have the problem and I DON'T in other words:
Without logs => No bugfixing because i can't see shit.

Also have you tried that with ONLY IC2Classic? No other mods installed and reproduced it?

Ok i testing..

okay, i test in clear Forge + IC2 CLassic, logs

client: latest.log
server: latest.log

The error still remains.
