Thanks for the report and error logs. I've forwarded this to Nate.

I'm not able to reproduce the problem. Can you outline more specifically the steps to make the crash happen?

Same problem here... I tried the last 4 or 5 versions and does not work... Any suggestion? Thank you! Looking forward for a fix.

Edit: To be slightly more specific When pressing the + button to add a bounding box and typing in the name. The moment I hit enter it crashes.My old projects with bounding boxes still function perfectly fine. Its simply the act of adding one. I can however copy and paste an old bounding box and rename it.

Confirmed the bug happens when you hide slots in Tree view by clicking the slots button up top.
Then adding a new slot, and then adding a new bounding box.
In that case, I guess it goes nuts because the parent slot is unselectable. Every attachment is supposed to be in a slot.

I've found that crash happens when I have selected bone, not slot. Here is video:

Good find. Thanks for reporting.
I guess the core of the bug is that those options shouldn't be there if a slot isn't selected.

No no, it was working before and Spine first asked about slot name, next Skin placeholder/Bounding box name and it was good

Ah, I didn't know that.
I wonder what went wrong with the code.

Anyway, at least we know one thing to avoid for now until this gets fixed.

Sorry for all the trouble guys, I was away visiting family. This is fixed in 3.1.03!

It works! Thank you!
