A new griefing method ruining games.

Please help me bring attention to this issue, we worked hard on building a FoB and the enemy team simply switched teams, grabbed hammers to destroy the gates at the entrances then built Climbable HESCO Blocks on top of the gate foundations. (one by one because then u can't build Bremer Wall on top to quickly stop this), then their team climbs the entrance and overload your base with easy access while they switch teams back to their original team.

Since switching teams is so easily doable there's literally no punishment to doing this.

Suggested fix: Once a round starts and you pick your team, DO NOT allow switching of teams. Lock people into their teams, even if they leave the server and re-join put them back in the team they picked.
