Problems in 1.8

My game file is here:  https://www.dropbox.com/scl/fi/hq7c3hisnd4a8ayg6svc6/anomaly-msg-endless-res.GC4Sav?rlkey=fzdgd5z6xhy8j8jp9bz54gscp&dl=0

I noticed 2 things. 

1.   when the turn is starting, I get multiple messages: only ships with a survey module can survey anomalies.  I had thought maybe this ocurred when I attacked a defended anomaly and my survey ship was destroyed.  So the fleet just keeps trying.   I get from 2-5 messages on turn starting every turn.

2. At the turn of this save, I just finished researching drive optimization, which is the last tech in its series.   I will now see this pop up as an  option regardless of whether I have actually already researched it.   This is probably just that the research tree is not fully worked out, but whatever.

I hope this may be of some help. If you want this sort of thing in a different way, please educate me.
