Hello, first post here, sorry if wrong formatting.

Basically, when opening crafting menu, selecting to "create item" and then pressing Esc, the game crashes.

When I did it after running IVAN from terminal, I got this message:

vilius@vilius-ThinkPad-T430:~$ ivan

I am running v0.58, on Xubuntu 18.04.4 and I have compiled the game myself.

Maybe zero or NULL volume got passed to the Forge Item recipe when you escaped from it and that caused a segfault?

Thanks for the report.

Hi winsalot! Welcome to the forum.

I love the way your IVAN dev work over the years has made you into a great programming guru Holybanana always wanted IVAN to be a vehicle for others to learn C/C++

Thanks for looking into it.

I had some more segfaults today. (I really hope they were not related to my safescumming haha)

In particular, game would often segfault when Mirror Imps would hit me (or maybe I hit them?).

Also, GC7 (the mystic one) was almost unplayable because of segfaults that seemingly would happen out of nowhere.

I could share my savefile if that would be helpful.

IVAN definitely got me into programming. I think it's admirable how simple and transparent the code is. You can understand many parts without any knowledge of coding and then delve deeper. And the community is great, too.

I still feel much more confident with Python than with C++, but maybe I'll get there in time.

Nothing should break if you're savescumming by copying your savefiles elsewhere and then back once you die, unless you don't copy all the files.

I'll have a look at the mirror imps. I think there might be a problem when a magic beam other than from a wand hits them.
