Base has completely disappeared

Really? I spent days to build my base and I just away for few days on holiday and lost everything.

I chose a PVE server because I didn’t want to lose my construction. I understand that has to have a system to take care the abandoned constructions, but six days is a short time.

And also, where are the information about the decay time? I tried to find it on the server description and in-game as well, but I didn’t find nothing.
