Please provide full log.

I do print the stacktrace, but the error is actually handled : [ProxyAccess] Proxy wold instanciation failed.
This happens when using Cauldron and it limits functionnalities when disguising vanishing blocks (walls or stairs may not appear connected for example).
Thanks for the feedback anyway :)

It's not really fixable as Cauldron apparently modifies World.class at runtime. Maybe I should just print the message instead of the whole stacktrace in log.

How would one fix that error? And no problem, I don't normally do that, but I like your mod(s) a lot.

As far as I'm concerned, there is no crash.

That'd be nice; any way to prevent crashes?

It somehow managed to crash my server... Maybe not.. That's odd. Looks like no reason for the crash..

The server stopped more than twenty minutes after the message I put in the log, so you can be sure it's not the cause.

You mean no crash from your mod/that it is a Cauldron problem?

I detect that there is an issue when instantiating my fake world and cancel it. In game, you can't see the difference as it's just limiting some functionalities. The game doesn't crash and continues on.

Wow, derp, sorry I forgot to pay attention to the time. Thanks, I'll leave ya alone; have a nice day!
