Update - enabling the raid window system effectively removed the DBD raid protection, period, from what I saw. So trying to add a raid window where building damage turns off before server reset, then turns back on after reset, thus trying to game whatever was making raid protection come off, did not work. In fact, while there was supposed to be raid protection due to building damage going off after a certain time, did not work - you could still damage buildings outside raid window. There is definitely something hosed up here.
The closest we can get DBD to work, is utilizing DBD as the ONLY raid system, and just avoid server restarts until you have to…
