yup, always got mad when I finally had enough salvage to craft an item, place it, only to find out i get booted and the item is lost. Petitioned it and got as response "yes, this is a known issue which is being worked on".
"god, how many devs did hami have to sleep with to get ED?"

Aye got a petition in to try get the item back lol.
Yeah we just had the same sort of problem...it rmoved our Hospital pods and our beacons for our Teleporters, soddin annoyin if ya ask me 
Has anyone else found that during the various times that the base boots everyone out, it also seems to undergo a small rollback?
A few times things have mysteriously reverted to their former layouts after being changed.
Sadly one issue have found with this, is while bought items, you can just buy and place again. Recently we placed a bunch of salvage made items, such as the tree of wonders. When the base returned to its former state, the tree was gone, the prestige returned and the salvage lost.
Anyone experiencing anythign similar?
