This is the second time this has happened. The first time I logged in and found all my item frames and items on the ground. Now they are just gone along with my items. I lost a lot of expensive items. Is there going to be a fix for this?
Correct me if I am wrong but, this sounds like it is in town. ;-) Item frames are buggy. I lost some items randomly from them and refuse to put anything worth more than a couple hundred rupees in an item frame anymore. which is kinda sad.
I have one logical explanation. Item frames are considered to be entities. A senior staff or admin could have done /stoplag or the EMC version of it. /stoplag removes and stops all entities such as mobs and red stone. When they did that the item frames would've been broken. That's all I can think of.
