This seems to happen when trying to move a player to a roster-size limited team such as MLB. This also happens when waivers are disabled. In this case, players disappear when they move to any team. Again, it seems to come back to normal when you allow AI teams to make moves, but this is really hampering roster creation and because I have not yet tested online leagues, I'm not sure the effect of this.
