rash Collector removing powered up grids not connected to base

Hello everyone. I searched internet for a solution but after 4 hours of searching I gave up. Since today, our server is deleting grids that we get out with "F" key and they aren't connected to base (batteries are on and status is Recharge or Auto). I searched the logs and I found the following :

17:39:09.9544 [INFO] Keen: Trash collector removed grid '86862612823823977:Mega Miner PAM - Adjoint' with entity id '86862612823823977'

I respawned the grid (same experiment happened with other 2 grids), I connected it to base, then I disconnected it and went to mine. I pressed F to get out and the grid started flashing red and server deleted it. I have almodt 500 hours in this game (almost all of them at the server) and it is the 1st time that happens. I am 100% sure that nothing changed at server. Also there was no update at mods , so it is not s/th that I can go to the MOD creator and report it. I even tried to restart he server but problem wasn't fixed. Disabling automatic work of Trash Collector and execute the cmd manually from Admin (at least that is what I found on net) isn;t a really true solution because it is the 1st time that happens after 500 hours of server being up.

Please note that I am talking about grids that have batteries on and battery status is Recharge or Auto and problem appears after they get disconnected from base and we get out of grid. Just in case someone asks, we get out because PAM is on or to check grid.

Thank you in advance.
