Consistent crash - [trade] Unexpected viewscreen. Bailing.

[mattregul]

Describe the bug
DF has been closing consistently with fresh embarks or old saves, after 5-10 minutes.

• 100% repatable
• no custom commands
• just entering enable df-ai at title screen and letting it do it's thing

What happened
DF crashes around the time we're trying to trade?

Was there also a file named df-ai-debug.log?

[mattregul]

Unfortunately no, not for this issue.

[mattregul]

is there a custom build I could run to pull more detail?

stderr.log

df-ai.log

[mattregul]

Removed blueprints folder, activating legacy mode. Crash still occurs. So, unrelated to "blueprints"

[mattregul]

This morning I redownloaded the latest from buildmaster (180821000) and it seems to be working.

Soooooo, maybe this is just a one-off issue?

Close for now?

The reporter should maybe not have closed this. In the latest release, I am able to reproduce exactly the same behavior, in particular this message upon encountering a trade:

[trade] Unexpected viewscreen. Bailing.

df-ai.log
df-ai-debug.log

However the contents of df-ai-debug.log appear to be related to an earlier, non-fatal error having to do with customizing a squad whose units could not be found.

Can you get rid of the debug log and allow it to be recreated when this issue occurs just to make sure that message isn't relevant?
