I “Fake” rounds in multiple of my maps for the very reason of how bad the round change over time is. (You will literally loose players as they wait for the black screen to change over)
As long as you are clear on when the round will end (Time based / Objective based / etc) then I feel you can do better then the round system in place.
When I have things that need to get reset this is how I handle it: My GameManager (Verse device) will include a ResetTrigger editable variable that I Trigger in verse when I’m ready to do clean up. Then my devices I either want to disable or enable, item removers that need to take player items, portals that need to relocate players, all listen to the ResetTrigger. This simplifies the control flow of the state of your game loop.
You will of course have to handle resetting other things in an appropriate way as well. For example some of my verse devices will listen to a reset trigger (or have a Reset function that gets called by some other device directly) then the device will do something like clear an array or change a variable the is referenced to a player in a map, etc.
