I have destroyed newbie protection wall and seen that time I can't leave my room, may be this is an issue?

I try to use variations like this:

creep.moveTo(Game.flags.flag_in_other_room)

var exitDir = creep.room.findExitTo(target.roomName);
var exit = creep.pos.findClosest(exitDir);
creep.moveTo(exit);

In both examples creeps goes to the wall and started to blink between rooms.

It's seems that creep event not appear in other room because they are doesn't executed on next tick after moveTo
