I don't know if anyone already reported this as I couldn't find anything.
I noticed A possible error with the tool tip when I was about to strip a Terran World and that was that I ended up getting almost 4 times the resource the tool tip told me I should get. I paused just before the stripping was done and emptied all my resource storage and the 2th picture is what I had a second later which is just short of being 4 times higher than what the tool tip told me.
At the time I also had 38% fleet upkeep, and both of the salvaging techs in case those factor in too. A modder told me that a Terran planet in the code should give 13,400 Credits, 6,700 Metal, and 3,350 Crystal.
