Tested the new trainer. Everything works including freeze timer. Activate it when 'scavenge timer' runs. The needle will still move but the nuke will not explode. Gather whatever items you wish to gather and after you're done, deactivate the freeze timer WHILE in the clear zone. Let the timer on the top right run 1-2 rounds, remain in the clear zone and you should be able to automatically hop into the bunker. (worked for me)
