Errors on game load (but seems to proceed)

The following 3 windows of tracebacks appear on loading an existing game. Game was created 2-3 point releases ago; gameplay doesn’t seem impaired. This is the Steam Latest alpha channel, updated today to r848.

Steps to reproduce:
Load my save game :slight_smile:

Expected Results:
A loaded game!

Actual Results:
A loaded game! And some screens of debugging messages.

CTD when I clicked on the “harvest” menu.

The error messages look like backward-incompatibility with old versions of the new builder. The crash it’s hard to tell - can you upload the log and crash dump?

Sure, attached. (54.7 KB)
stonehearth.log (85.5 KB)

The crash should be fixed in the next release. The building error I will pass on to the building folks.

That was fast o.O what was it, that you identifed in 30 seconds?? lol

Oh - also, would it be valuable to have a new game where only the current version of the new builder is being used, rather than potentially rediscovering the same thing?

It’s the same error as mentioned in another thread that I’ve already fixed.

Ah gotcha. I’ll set that save aside then.
