As suggested on the Steam forums by Gordholm, there might be a bug with the offline module on the (rough) CV I built recently. Steam thread linked below (complete with a couple screenshots). As suggested by Gordhom, it might be a bug with the Offline Protection module on the ship. As I type this I just realized a pattern to when the force field is showing up. Each time that I can confirm it happening was in a PvP area (Ningues, Skillon, and the "North" Trading Outpost). I've also posted the entire Save file for the server (I host it on one of my own computers). The ship currently is at Oscutune under the name, "Building Barge" at approximately (-32, 74, 2547) @ 51m. You can also log into my character (ending in 46) and I'm just inside the base where it's docked at on the planet's surface. I've also uploaded the entire save file (including the cache folder, just in case) into my Google drive. https://drive.google.com/file/d/1yFI2WqFaCCYgbcY3nmIaNT3GwgbMYA5R/view Original Steam posting w/screenshots https://steamcommunity.com/app/3831...8156542/?tscn=1548345263#c1742232339928290403
Two users on my server have also reported that their Offline Protection went active while they were still online. Exiting to desktop and logging back in seems to correct it.
The latest exp build 2203 has a fix for this https://empyriononline.com/threads/alpha-experimental-9-3.47312/
