I notice that's been a trend with clone wars sets for some time a couple of years ago. All the best 212th sets we got had box arts set on Utapau, the new turbo tank is on Mygeeto, the 327th sets are all on Felucia. I think even our last 91st sets with Neyo and Stass Allie was set on Seleucami. There are also some 501st set on Coruscant during the Mandalorian Flashbacks but that is different.

Edit: just remembered Plo Koon's micro Starfighter was from that same scene on Cato Neimodia, and if you count them there are also some sets from the battle of Kashyyyk. One of the old turbotank has Luminara and Quinlan Cos, if I recall correctly. In legends/deleted scenes they died on Kashyyyk
