With how unstable this game inherently is (badly optimized, bad netcode and numerous other issues) Chaos Wastes desperately needs some kind of checkpoint system where you can experience a crash but still able to continue where you left off or close to it.
All night tonight (about 5 games) both me and two of my friends who plays this game has experienced crashes to desktop, lost connection to host and a bunch of other issues that resulted in all progress lost without actually dying or failing the expedition.
Just now my friend who hosted got crash to desktop on last event on an expedition. 1-2 hours of wasted time since host migration failed and everyone else got booted out to Pilgramage Chamber without any means to continue.
I do not mean a checkpoint system for dying or failing. But one for disconnects, crashes and other problematic things (like getting kicked at the very end).
