code is buggy and not working ideally, especially in "guess the build" mode

Simply I help optimize it here: https://github.com/mikechenczy/buildbattle
I made "options menu" available in "guess the build" mode. I made the mode not always in one plot so that we can store the build in each plot and we can appreciate the winner's at the ending. I also fixed little bugs like some placeholders not working correctly and in guess mode guessers not being in spectator mode which seems a more appropriate mode.
Still one problem I'm not able to solve is that changing biomes in "options menu" not working well when the server use plugins like viaversion to support multiple versions, I tested on 1.19 server and on minecraft of high versions it works well while on lower ones like 1.8.9 I tested on the biome never changed. I searched for information but still I can't solve it.
