Yesterday night (linux, pre-patch) I was doing the advanced combat training mission. On logging in again this morning (post-patch and different linux computer) the mission I was doing is just called "Mission" and has no text, not in the mission list or in the mission/advancement logs. Aborting the mission causes everything to be normal again.

(screenshot looks a bit weird, I used the system tool rather than the one built into VO, but on screen everything is fine)

Advanced combat practise allows multi-session. Did you try and kill a bot and see what happens?

Also that's an awful screenshot, lol, next time use /dump

I've seen this happen too. It does that when you take a mission that doesn't end when you log off on one device, then log in on another device that doesn't have your character's mission log file from when you started it.
