Use any of the appropriate tools to place a garden plot. After the interaction process is done a hologram is left instead of an actual viable garden plot. I’ve seen this issue in the past after reading but could not find anything that went to a resolution. I do/dead have build anywhere mod however removed it prior and modified the CFG gameplay files instead and removed I do think that is purely coincidental but not sure. I can place a viable garden plot with admin tools but that is the only way
