I think the title explains everything but here we go: When you die and your bed is broken on bedwars, you become in gamemode creative and get vanished being in creative allows you to spec block, so my idea is to change the gamemode from creative to Spectator or Gamemode3 as some know in order to stop the spec blocking. Specblocking: when a spectator stands infront of a person building a bridge which causes the block not to get placed and the builder to fall into the void. (this is considered trolling/glitch abusing, and you can get banned for that as the bedwars rules also stated that it is bannable).
Support yes omg i hate when killing off a player with no bed then i have to be cautious when building
