Ah YES i suspected that the MALL and structured city ploting from the new update would be an issue. This is has become apart of boundless organized groups with in a sandbox. I can think of a few ways to fix the new reserve plots system, to accommodate this. thanks MajorVEX for the screenshots of detailing out this issue.
I think when removing plots, the reserved status should goto who removed the plot. a holder beacon should not beable to claim plots upto another reserve plot and over take the claim on the reserve status.
Also reserve plots should be setable in terms of turning off certain parts as in MajorVEXs MALL so parts do not get reserve. also to addin reserve plot authorized to let players now do a control change over of plot claims with one dropping plots, then authorizing that player on that beacon to be able to claim reserved, thus allowing that other player to beacon on a reserved.
Again need to have reserved plot setting options features. would be like plot zoning data.
if anything this should get address soon, or the current cities and malls will suffer and get ruined for prolonged period of time.
