Formerly, I could copy text from Missive, paste into a plaintext field, and have linebreaks preserved. Now, they're only preserved if I paste into a richtext field; text becomes one big run-on paragraph if I paste into a plaintext field.

Before I would:

1. Copy from Missive (an email or a Response).

2. Paste into a plaintext field (such as in AutoTask, which only accepts plaintext).

Now, if I wish the same result I have to do something like:

1. Copy text from Missive.

2. Open a draft in Gmail to get a richtext field.

3. Paste.

4. Copy from Gmail draft.

5. Discard draft.

6. Paste into a plaintext field (such as in AutoTask).
