Tank spawn transfer bug

At round start select a tank, but don't spawn. Wait until your team got your home flag. Now you can't spawn with the tank and the enemy team gets an additional tank. Your tank got "transferred" to the enemy. After that transfer the tank spawns are messed up. In this round the enemies got 3 additional tanks (2 tanks at a time). It took long until we got our first tank spawn. We destroyed 2 of those additional tanks and our home flag got taken and recapped twice. And after our tank spawned, the enemies even got their 3rd additional tank spawn. Similar, but different problem here on Sinai: https://youtu.be/SjkM0qRm6Gk
