What's Wrong?

/compact or auto-compact is making latest response and some times parts of a response disappear. This is happening always.

What Should Happen?

latest responses just before compaction should exist for user's (my) context and never disappear. In the attached image, everything after "Problems:" disappeared, leaving me guessing !
