Resolved.

Thx Prosper for beta testing. There are still some obfustated methods I use as the mappings are not available yet, I'll have a detailed look at this and try find the cause.

You were absolutely right: Client side method access in the server, problem source: Container GUI name getter. On my dev machine the local server did not complain, so I hope this is fixed.

Could you also double check when you have time and confirm that the issue is solved? thx
