are you getting the new vanilla rover rather than the custom scrap rover?

ive redesigned and dated splitsies rover and it fixes this problem on my server but you do need to do 1 other thing to the Satreus mod too:

Update info for use on Scrapyard Survival Scenario (depends on re-spawn mod used)https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=3546786949

make sure rover mod is at the top for torch ran server list, bottom for coop/dedicated server,
go into this mod, 244850\2266665708\Data\RespawnPodEdit_LowAtmo and you need to edit the xml code,

find this line of code <Ship> <!-- Planetary Rover -->
edit the line to this <Ship Enabled="false"> <!-- Planetary Rover -->
then save the xml and restart your server

this should fix the problem for some/most servers were the vanilla rover and/or custom rover are spawning on all planets
