I've been speedrunning some Lethal Zone in the solo + no boons/no legacy survivors category and also been testing out how to have the trader missions spawn in as quick as they can. I've found out that the New Beginning mission spawns instantly if you previously left the game once at any time before killing the last plague heart. This happens because rejoining the game grants the ''Promote a Leader'' mission to pop up, this makes the New Beginning mission spawn in instantly after leaving the game again and rejoining when completing the Cure for All Seasons mission. However, there's a rule which states that you are not allowed to leave the game until you have killed every heart. I just want to know if doing this strat is allowed. From the New Beginning mission spawning to completing the legacy, my potential best time would've been somewhere under 13 minutes, it instead took me exactly 15 minutes because I didn't have a suppressor for my gun which prolonged the summit mission. Sidenote, calling in survivors after completing the Cure for All Seasons mission prevents other missions from spawning, which prioritise the legacy missions to spawn. This remains even if you continue to leave and rejoin. I have a stream of me doing the entire strat at the 1:18:18 timestamp if you want proof I just want to know if this can be allowed
