EchoView tells me the max ammount of clans I can land in a planet with bad temperature, but the clans are deading and eating supplies. Do I have to make some setting in the EchoView to update this game in particular?

The default PHost configuration value for MaxColTempSlope is 1000 and that gives similar (but not identical) max population on "normal temperature" planets (15<=temp<85) but the max population is about half or less on extreme-temperature (hot or cold) planets. You can see the numbers for both here: https://www.vgaplanets.ca/vga-planets-calculator/#growth_table change the dropdown from "TimHost" to "PHost" and that should match the behavior you see in the game.

I'm not familiar with EchoView (I use VPA), perhaps there is a configuration setting to switch it to PHost mode?
