Multiplayer — Competitive mode temporarily disabled

While working on Co-op mode, we found several bugs specific to Competitive mode (match end and progress tracking weren't working reliably, among others). To make sure nobody runs into these mid-match, the "Competitive" option is temporarily disabled when hosting — only Co-op is available when creating a lobby right now.

Existing saves are not affected. Competitive will return once the remaining issues are fixed.

Server hardware upgrades — back to a fixed chain

The previously introduced free choice among all compatible components allowed replacing a part with a weaker (and cheaper) one — effectively downgrading your own server. "Upgrade" now automatically leads to the single next tier in the defined chain again, with no selection screen.
