Dungeon Master Forum

Edit any item, and click the Add button to add items into it (it doesn't matter if it's a container, or a trigger, or anything else). This pops us the Container Builder window. If you close this window by clicking the [X] close icon, the whole of ESB will close, no errors or anything. I've lost quite a bit of work this way as I hadn't saved before entering that screen...

It doesn't do this for me.
I guess I'll need a little more information if I'm going to figure out what's happening...

I'm getting the same problems when I try adding an item to a champions inventory in the roster: ESB closes immediately that I select an item -- no errors generated.
It does it in the test dungeon, easy to replicate: go the the champion roster, select the firs Test character, select "Add to Pack" and select an item from the list: instant crash.

Sorry about that. It's pretty much unusable.
Here's the version of ESB I'm going to include in DSB 0.52. Just use that one instead.
