It seems that when this plugin writes to the zone manager data file and RB goes to pull all available base locations it always comes up with 0 so none spawn. I do have a pvx plugin running for pve to pvp zones which writes to the same file. When I only run the pvx plugin RB runs fine. It is when landlord writes to it where it messes up RB so I know it isn't raidable bases. 

I'll check it

RM is a very complicated plugin, I can't prove it but it appears an RB issue, not Landlord. 
May be information from the help section of RM plugin is relevant

This plugin does NOT use Zone Manager - it creates and manages everything on its own. If you are having issues with too few locations on the grid, or each attempt to spawn a base returns a manual spawn was already requested then it is likely because of how you have setup Zone Manager. You either have far too many zones, or you have zones which are far too large. Raidable Bases will not spawn in these zones unless the ZoneID is added to Allowed Zone Manager Zones in the config file.

I am having this same issue.. how did you fix it?

Every banner placed on my map creates a zone in the "Zone Manager" Data file and you even list "Zone Manager" in the Dependancies so that statement is wrong.
What is happening is that these zones prevent RB from adding the area on the spawn options. So once you restart RB there are no places to spawn in bases at. Not sure which one of these 2 mods needs to change but they conflict for sure.
