im not sure if anyone has found this yet but ive found another way to float objects without having to save and quit or have someone hold another object in the air, since we all kno these can be anoying. ive found that if u end the round and after the round ends, but before the next one starts (as the voice of death states "round over") someone creates an item it will not drop to the ground so u can quickly throw it into place and it will stay floating. although im not sure whether or not u can do this with one person i will test it soon but in the mean time this can become very handy when trying to get items to float just right since it is a time saver.
A while ago I think somebody posted this same thing. I also heard that you can have someone drop a grenade on it with another controller and it will float. maybe thats just me.
Nice find, but I don't think it will be utilized much. Most forge objects have to have time spent to place them
